What is Enterprise Manager? 
Enterprise Manager provides you with an easy Windows-based way of monitoring and managing 3Com network devices and PCs on your network. By using color-coded representations of manageable devices, you can quickly identify their status and any action necessary to solve problems. WorkGroup PC Links management tools provide management of PC network activity and information. A toolbar enables you to access the most frequently used Enterprise Manager functions with a single click of the mouse button, rather than using the menu system. 
Enterprise Manager accurately shows you the number and type of units making up a supported device (for example, an FMS stack), shows you the status of individual ports, and allows you to collect detailed device and port statistics. The statistics show you network usage and trends in easy to read graphical displays. 
Status and error messages from devices are displayed in an event log. Messages are color-coded by severity and you can add notes to them for later reference. A search facility allows you to find messages based on different search criteria. 
For you to be able to monitor and manage devices, you must create a graphical representation of your network. Enterprise Manager makes this easy for you to do by dividing your network into groups of 254 devices, automatically finding out what devices are in each group, and adding an icon for each device on the network. All you need to do is to tell Enterprise Manager where to look for the groups of devices. Enterprise Manager also discovers PCs running PC Links SmartAgent software, which enables you to invoke the WorkGroup PC Links management tools. 
In addition to the detailed monitoring and management of supported hubs, bridge/routers, and PCs, you can use Enterprise Manager to monitor the status of a number of other network devices, again by the use of color-coded icons. Although you cannot manage these devices with the same graphical-style interface provided for supported devices, Enterprise Manager provides a Telnet user interface so you can access the local management interface for the device. 
How Does Enterprise Manager Work? 
Enterprise Manager works by creating two types of views on your network; Network Level views showing the connections between the subnetworks and Subnetwork Level views showing the actual devices on a network. The advantage of dividing your network like this is that it enables you to use Enterprise Manager to represent the exact hierarchy of your actual network. 
At the lowest level, Enterprise Manager assumes your network comprises one or more groups of up to 254 devices, the groups being connected together by IP routers. Each group of 254 devices (or subnetwork) can be a Class C IP network, or a Class A or B IP subnet. Enterprise Manager shows the connections between these subnetworks at the network view (or Level 1 window), which is a high-level view of your network. Successive levels provide views (the Level 2 window, Level 3 window, and so forth) that are progressively more specific. The window containing icons that correspond to manageable devices is commonly referred to as the subnet view. 
Double-clicking the icon that corresponds to a manageable device opens a window containing a graphical representation, or external view, of the device. The external view can be interrogated for detailed configuration information on an interface-by-interface basis. 
If you are setting up an IP network for the first time, it is important that you choose a class of network that is appropriate for your future, as well as your current needs. This depends on the number of nodes you have and whether or not you intend to connect your network to others on the Internet. If you are unfamiliar with TCP/IP and Internetworking, please read Getting Started with Internetworking. Remember, if you want to have more than one group of devices, the networks (either Class C, or Class A or B subnets) need to be connected together by IP routers. 
When you begin working with Enterprise Manager, you need to tell it what groups of 254 devices make up your network. You do this by creating a Network Level view and adding icons to it representing the Class C networks and Class A or B subnets. Enterprise Manager does not require you to tell it what devices make up each subnetwork; once you tell Enterprise Manager the address of the subnetwork, Enterprise Manager can automatically discover the devices and add an icon representing each device to the Subnetwork Level view. 
Enterprise Manager uses the Simple Network Management Protocol (SNMP) to manage supported devices on your network. Information gathered using SNMP is used to display an accurate representation of a device, including the type of units and the status of individual ports. 
Although Enterprise Manager uses TCP/IP to communicate with devices on your network, if you also have IPX installed on your PC, Enterprise Manager can find devices using IPX and add them to your subnetworks as well. Using IPX alone, Enterprise Manager can manage FMS and FMS-TR devices and can detect, but not manage, the status of other IPX devices. 
IP Subnets 
This version of Enterprise Manager does not display large TCP/IP subnets on its network view. Therefore when you define subnets in Enterprise Manager, you must specify the first three octets in full, splitting class A and B subnets into class C-type subnets in your network view. This allows up to 254 TCP/IP devices per subnet. See Working with Networks for information on creating network views. 
Example: 
The subnet 125.5.132.0 uses the subnet mask 255.255.252.0. It contains all the following hosts: 
·125.5.132.1 to 254 
·125.5.133.1 to 254 
·125.5.134.1 to 254 
·125.5.135.1 to 254 
Using this subnet mask, host addresses are defined by the eight bits of the last byte plus the two least significant bits of the third byte of the address. This allows for a total of 1016 host addresses (4 x 254 = 1016) per subnet. 
However, the Enterprise Manager auto-discovery process uses only the last byte of a specified subnet address so a subnet can contain up to 254 TCP/IP devices. You must, therefore, configure additional subnets (one per 254 addresses) for addresses that use bits within the third byte of the subnet address. 
You need to create four subnets, 125.5.132.0, 125.5.133.0, 125.5.134.0 and 125.5.135.0. These appear in Enterprise Manager as separate subnets even though they are part of the subnet 125.5.132.0. 
Starting Enterprise Manager

Configuring Devices for Use with Enterprise Manager 
In order for Enterprise Manager to be able to communicate with devices using IP on your network, you must set up the device with the following information: 
IP address The device must have a unique IP address. If you are unfamiliar with TCP/IP addressing, refer to Getting Started with Internetworking. 
Subnet mask You only need to enter a subnet mask if you have implemented subnetting on your network. If you are unfamiliar with subnetting, refer to Getting Started with Internetworking. 
Default router IP address If you have a router connecting your network to other IP networks, you must enter its IP address. 
Use the device's local management facility to set these parameters. Refer to the guide(s) supplied with the device if you need information about how to do this. 
NOTE:Some devices (such as ECS hubs) require other parameters to be set before they can be managed remotely. Check the relevant chapters in Volume 2 of this guide for any additional information. 
Creating a New Network 
You can create a new network at any time while you are working with Enterprise Manager. Each network you create is managed and monitored separately. You may consider creating more than one network with Enterprise Manager if you have a large network and want to manage parts of it separately. Or, if you have more than one person using Enterprise Manager, you could create a separate network for each of them to manage. Although a device cannot appear on a network more than once, the same device can appear on more than one network. 
NOTE: Remember to add separate users for each person using Enterprise Manager and to set a password for the user "admin" to ensure the security of your network. 
To create a new network: 
1From the File menu, choose New. 
Enterprise Manager displays the New Network dialog box, shown below. 

FIG 
Figure 2-1 New Network Dialog Box 
2Enter the network name and a network password (if required). 
3Click on OK. 
Enterprise Manager displays an empty Network Level window; it is from here you are able to create a representation of your network and manage devices. Each network can comprise up to five levels, allowing you to represent complex subnetted networks. 
In the New Network dialog box: 
Network Name Provides a box for you to type a name for the new network view. The network name can be up to eight characters long and is not case-sensitive. 
Password Provides a box for you to type a network password. Enterprise Manager does not require you to use a network password, but by using a password you can prevent unauthorized access to the network. The password can be up to 20 characters long, and unlike the network name is case-sensitive. For security purposes, Enterprise Manager does not display the password when you enter it. 
CAUTION: If you create a network password and then forget it, you cannot access the network. If this happens you must delete the old network and create a new network. 
Opening a Network View 
Before you can work on a network view, you must open it - that is, you must display it on your screen. Enterprise Manager allows you to create more than one network, but you can only have one open at a time. 
To open a network: 
1From the File menu, choose Open. 
The Open Network dialog box is displayed, shown in Figure 2-2. 

FIG 
Figure 2-2 Open Network Dialog Box 
In the Open Network dialog box: 
File Name Lists network files in the current directory and provides a box for you to type or select a filename. 
List File of Type Lists the file formats supported by Enterprise Manager. 
Directories Lists the directories available on the current drive. 
Drives Lists the drives available on your system. 
NOTE: If you have more than one network, you can use the Set Default command on the File menu to choose one of them to be opened automatically for you whenever you start Enterprise Manager. 
2In the File Name box, type or select the name of the network you want to open. If you do not see the name of the file you want, select a new drive or directory. 
Enterprise Manager displays the Network Password dialog box, shown in Figure 2-3. 
3Enter the network password (if required). 
Enterprise Manager displays the Network Level window; it is from here you are able to create a representation of your network and manage devices 

FIG 
Figure 2-3 Network Password Dialog Box 
Saving and Deleting a Network View 
When you open a network view, Enterprise Manager copies it from the disk and displays the copy in the Transcend Enterprise Manager window. As you work and make changes to the network view, you are actually making changes to the copy of the network view temporarily stored in the computer's memory. To keep your latest work safely on the disk, save your network at regular intervals. When you quit Enterprise Manager, if any changes have not been saved, a message asks you if you want to save the changes. 
To save an existing network view: 
From the File menu, choose Save. 
You can use the Save As command to create more than one version of a network view and to save copies to another disk for safekeeping: 
1From the File menu, choose Save As. 
The Save Network As dialog box is displayed, shown in Figure 2-4. 
2In the File name box, type a new name for the network. 
3If you want to save the network to a different drive or directory, select the drive or directory, or type the complete path in the File Name box. 
In the Save Network As dialog box: 
File Name Provides a box for you to type a filename for a new file. 
Folders Lists the directories available on the current drive. 
Drives Lists the drives available on your system. 
Save File as Type Lists the file formats supported by Enterprise Manager. 
When you no longer need a network view, you can delete it to make the disk space available for other network views. Use the Delete command from the File menu to delete a network view. 

FIG 
Figure 2-4 Save Network As Dialog Box 
Displaying and Using the Tools Box 
The Tools box contains the tools and utilities you use to create and update networks. 
To display the Tools box: 
From the Options menu, click Show Tools. 
Enterprise Manager displays the Tools box, as shown in Figure 2-5, in the bottom left corner of the active window. 

FIG 
Figure 2-5 Tools Box 
When you have Show Tools selected, the Tools box always appears in the active network or subnetwork window. When you deselect the window, the Tools box disappears. The Tools box contains the following tools: 
Subnetwork Adds a subnetwork to the network view. Your pointer changes to a cube. Position the pointer at the location you want to add a subnetwork and click the left mouse button. The subnetwork icon appears in the active window and is color-coded blue to indicate that it is unconfigured. To configure the subnetwork, see Configuring a Subnetwork . 
Text Inserts text on the background so you can annotate the network view. Your pointer changes to an I-beam. Select your insertion point in the window and type in your text. To change the font style and size, from the File menu choose Preferences and in the Preferences dialog box, choose Font. In the Font dialog box choose the font, font style, effects and color. 
Move Allows you to move subnetworks and nodes. Your pointer changes to a truck. Drag and drop the node or subnetwork you want to move. When you click on an object, the pointer changes to the icon of the object you are moving. The pointer returns to a moving truck when you drop the object. 
Erase Removes subnetworks and nodes from the network view. Your pointer changes to a pencil eraser. Select the object you want to erase. An Enterprise Manager message appears asking you to confirm the removal of the object. 
Map Adds a map background to the window images to help you show the physical locations of the elements of your network. Double-click on the map tool to display the Map Selection dialog box. Select the name of the graphics file you want as a map background. See Adding Map Backgrounds to Your Network for more details. 
Ethernet Draws a solid line between devices and subnetworks to indicate an Ethernet connection. 
Token Ring Draws a dotted line between devices to indicate a Token Ring connection. 
WAN Draws a lightning bolt between subnetworks to indicate a wide area network connection. 
For the Ethernet, Token Ring and WAN tools your pointer changes to a pencil point. Select the first subnetwork or node object you want to connect. Select the second object you want to connect. Enterprise Manager draws the appropriate line for the connection. Connections are cosmetic and act only as a visual aid. You can hide the Tools box by either closing the Tools box window or by choosing Show Tools from the Options menu. 
Creating a Network: A Simple Example 
The example in Figure 2-6 shows how you would use Enterprise Manager to represent a network that comprises a single Class C IP network. Enterprise Manager assumes your network consists of one or more groups of 254 devices, each group corresponds to a Class C IP network, or a Class A or B IP subnet. Each group is represented on the Network Level by a subnetwork symbol; devices are shown on the Subnetwork Level, which you can display by double-clicking on the appropriate subnetwork symbol. 
To create a network similar to that shown in Figure 2-6: 
1Make sure the Tools box is displayed (from the Options menu, select Show Tools). 
2Select the Subnetwork tool from the Tools box. 
3Click in the Enterprise Manager window where you want the subnetwork symbol to appear. 
4Configure the subnetwork with the appropriate Class C IP network number and let Autodiscovery add devices to the Subnetwork Level. 
Read the following topics in this chapter for a detailed explanation of what you need to do next: 
·Configuring a Subnetwork 
·Letting Autodiscovery Build Your Network 
These sections describe the steps you need to take to enable Enterprise Manager to identify the subnetwork and discover the devices within it. 
NOTE:If you want to create a network consisting of class A and B subnets, see the section IP Subnets. 

FIG 
Figure 2-6 A Simple Network with Toolbox 
Creating a Network: A Complex Example 
The example in Figure 2-7 and Figure 2-8 show how you would use Enterprise Manager to represent a network that comprises three Class C IP networks. The corporation in this example has two offices; Main St., and Broadway. The Main St. office contains one Class C IP network, and the Broadway office contains two Class C IP networks (one used by Engineering, the other used by Finance). All the networks are connected together via IP routers. 
NOTE: If you want to create a network consisting of class A and B subnets, see the section IP Subnets . 
To create a network similar to that shown in Figure 2-7 and Figure 2-8: 
1Make sure the Tools box is displayed (from the Options menu, select Show Tools). 
2Select the Subnetwork tool from the Tools box. 
3For each office click in the Enterprise Manager window where you want the subnetwork symbol to appear. 
Read the following topics in this chapter for a detailed explanation of what you need to do next: 
·Configuring a Subnetwork 
·Letting Autodiscovery Build Your Network 
These topics describe the steps you need to take to enable Enterprise Manager to identify the subnetwork and discover the devices within it. 
4For the Main St. office, configure the subnetwork with the appropriate Class C IP network number and let Autodiscovery add devices to the Subnetwork Level. 

FIG 
Figure 2-7 Main St. Office Network 
5For the Broadway office, configure the subnetwork level but do not enable Autodiscovery to add devices to it. Instead, use the Subnetwork tool from the Tools box to add two more subnetworks (one for each of the Class C IP networks the office contains). 
6Configure the Engineering and Finance subnetworks with the appropriate Class C IP network numbers and let Autodiscovery add devices to the Subnetwork Levels. 

FIG 
Figure 2-8 Broadway Office Network 
Configuring a Subnetwork 
The Subnetwork Configuration dialog box allows you to allocate a meaningful name to the subnetwork and supply details about where the network is and who is responsible for it. 
To display the Subnetwork Configuration dialog box: 
1Select the subnetwork you want to configure from the network view. 
2From the Configure menu, select Device/Subnetwork. 

FIG 
Figure 2-9 Subnetwork Configuration Dialog Box 
In the Subnetwork Configuration dialog box: 
Name Provides a box for you to type a name for the subnetwork. When you add a subnetwork to a window, Enterprise Manager supplies it with a default name Subnetx, where x is a number representing the order in which the subnetwork was added. It is important that you change the default name to something more meaningful; use descriptive names, such as Development, Floor 1, or the IP network number. The subnetwork name can be up to 15 characters long. 
Location Provides a box for you to type the location of the network. The subnetwork location is not used by Enterprise Manager; it is just for your use and helps you to include more information about the subnetwork. 
Contact Provides a box for you to type the name, phone number, and fax/pager number for the person responsible for the subnetwork. The contact information is not used by Enterprise Manager; it is just for your use. 
Before closing the Subnetwork Configuration dialog box you need to supply details about your network in the other boxes. 
IP Addr Provides boxes for you to type the IP network number of the subnetwork. For example, if you want to manage two FMS stacks, one with an IP address of 191.1.1.35 and one with an IP address of 191.1.1.50, you must enter an IP network number of 191.1.1.0. The last IP Addr box always contains 0 because this is used to define the address of individual devices. If the subnetwork contains other subnetworks, for example if it is the subnetwork Broadway containing the Engineering and Finance subnetworks, only type the common part of the IP addresses. The IP network number must correspond to the network number used by devices you intend to manage. The IP Addr pull-down menu provides a list of IP addresses previously used on the network. 
Subnet Provides boxes for you to type the subnetwork mask. You only need to change this from the default supplied by Enterprise Manager if you have implemented subnetting on your network. 
Gateway Provides boxes for you to type the IP address of the IP router (gateway) connecting the network to other networks. If you have a network without any routers enter an IP address that is not used by any other device on the network, or 0.0.0. 
IPX Addr Provides a box for you to type the IPX network number. The IPX network number must be hexadecimal and can be up to eight digits long. The pull-down menu displays a list of IPX network numbers previously detected on the network. 
Perform Automatic Node Discovery Click in this box before closing the dialog box if you want Enterprise Manager to discover devices within the subnetwork. Automatically discovering devices is described in Letting Autodiscovery Build Your Network. 
Defaults This button removes any Location, Contact, and IP address information you have entered. 
NOTE: In the Subnetwork Configuration illustrated above, it is possible to enter both an IP subnet and an IPX network number for the same subnet. Autodiscovery first carries out an IP discovery and then an IPX discovery. This lets you represent mixed protocol subnetworks. An alternative is to have two separate subnets, one for IP devices and another for IPX devices. You may prefer this alternative as it indicates more clearly the protocol being used. 
Letting Autodiscovery Build Your Network 
The Subnetwork Configuration dialog box allows you to start the Autodiscovery program, which searches the subnetwork, and attempts to identify any devices it finds. Icons representing the devices discovered are automatically added to the subnetwork. 
To start the Autodiscovery program: 
1If you have not already, display the Subnetwork Configuration dialog box, see Figure 2-9: 
aSelect the subnetwork you want to configure. 
bFrom the Configure menu, select Device/Subnetwork. 
2Click the Perform Automatic Node Discovery check box. 
If Autodiscovery is searching using IP, Enterprise Manager asks you to confirm the range of IP addresses it is to search. As each device is discovered, Autodiscovery adds the appropriate icon to the subnetwork window. 
NOTE: When using the Autodiscover dialog box, do not press Return to start the Autodiscover process. This causes Enterprise Manager to prompt you for permission to add each node to your network view. Click on OK instead. 
You can use the Preferences dialog box from the File menu to specify whether the names given to nodes are generated by Enterprise Manager or are derived from information stored by the device. 
Generic nodes are generally devices that Enterprise Manager found through Autodiscovery, but was unable to identify because its agent was not installed or was unrecognized. 
If Autodiscovery fails to find a node that you know exists, it is possible that the node is not powered up with the agent running. You can add the node to the subnetwork by running Autodiscovery again when the problem is corrected. Restrict your search to the address of the device you want to autodiscover and select Append to add it to your subnetwork view. Alternatively, you can use the Nodes box (see Using the Nodes Box ). 
If you run Autodiscovery again, you may need to use the Configure Console dialog box from the Configure menu to increase the Time-out and Number of Retries. Increasing either of these values increases the time Autodiscovery takes to search the subnetwork, but can increase the accuracy. See Changing the Console Settings for more information on setting the time-out and retry values. 
You can stop Autodiscovery at any time by pressing any key. Enterprise Manager asks you to confirm the decision before stopping Autodiscovery. 
A PC running the SoftHub software found by Autodiscovery is shown on the subnetwork by a SoftHub icon. Double-clicking on a SoftHub icon invokes the WorkGroup PC Links which provides grouping views of PCs, including management of their network activity and asset information. 
Device Icons 
The table below shows the different icons used by Enterprise Manager to represent devices in the subnetwork view. The appropriate icon is used if the device is autodiscovered or you can select the icon from the Nodes box to place a particular device on your network. See the next section "Using the Nodes Box" for more information.

Using the Nodes Box 
The Nodes box contains the different types of nodes (or devices) you can add to subnetworks. You can use the Nodes box if you want to add a device to a subnetwork, but do not want to run Autodiscovery. To add a device, you must know its IP address or IPX address. 
To display the Nodes box: 
Open a subnet by double-clicking its icon. 
From the Options menu, click Show Nodes. 
Enterprise Manager displays the Nodes box, shown in Figure 2-10. 
The Nodes box shows two node types at a time. To see more, use the scroll bar. When you have Show Nodes selected, the Nodes box always appears in the active subnetwork window. Selecting one of the node types turns your pointer into the appropriate node. 
To place a node on the subnetwork, select the appropriate node from the Nodes box and click where you want the node to appear. You continue to work with that node type until you select another, or deselect the node type by clicking on it once. As you add nodes, Enterprise Manager gives each of them a name based on the type of node and the order in which they were created, for example, Hub 101, Hub 102, and so on. 
To manage an FMS stack, LinkSwitch, ECS, MSH or FMS TR hub, NETBuilder bridge/router, or LANplex you have added, you must provide Enterprise Manager with the information it needs to communicate with the device. You do not need to add the default gateway information as Enterprise Manager uses the subnet's default gateway parameter to communicate with the device. Providing this information to Enterprise Manager is described in Configuring Devices for Use with Enterprise Manager. Each device must be set up for management, refer to the chapter "Setting Up Management..." in the user guide for each device. 

FIG 
Figure 2-10 Using the Nodes Box 
Displaying Information About a Subnetwork 
Enterprise Manager enables you to display a summary of the information about a subnetwork. This information is similar to that which you provided when you configured the subnetwork, but it is in a read-only form. To display the subnetwork summary information: 
1Select the subnetwork for which you want to display the summary . 
2From the View menu, choose General Info. 
The General Info dialog box shown in Figure 2-11 is divided into two parts: the Categories box on the left and the General Information panel on the right. When you select a category, the panel changes to display the information for that category. 
3In the General Info dialog box, choose the ID category. 

FIG 
Figure 2-11 Subnetwork General Information Dialog Box 
In the ID panel: 
Name Shows the name of the subnetwork. 
Network Shows the name of the network to which the subnetwork belongs. 
Type Shows the type of icon selected, in this case "Subnetwork." 
IP Addr Shows the IP network number for the subnetwork. The IP network number is the first three bytes of the number shown, the last byte is shown as 0 because this is used to define the addresses of the individual devices. 
IPX Addr Shows the IPX network number. 
MAC Addr The MAC address field is not used. 
 
Using the Edit Commands 
The Edit commands enable you to copy nodes and/or text from one network to another or to delete nodes or text from a subnetwork view. 
The Undo command enables you to cancel your most recent edit command or action. If you don't like the results of an action, or if you accidentally delete a node, choose Undo as the next action. If a command cannot be cancelled, Undo is grayed-out on the Edit menu. 
The Cut command enables you to move a node to the clipboard, removing it from the active window. You can place the node in another window using the Paste command. Unlike the Move tool in the Tools box (see Displaying and Using the Tools Box in this chapter), Cut and Paste allow you to move a node between windows, whereas the Move tool in the Tools box only moves nodes within the same window. 
The Copy command enables you to copy an object to the clipboard, leaving the original behind. You can place the object in another window using the Paste command. 
Cut, Copy and Paste are useful if you want to create network views for parts of your network for other people to manage showing only some of the devices in your network. In the example shown in Figure 2-13, the DEVELOP network is created from the MY_CORP network. The device MSH 1 is copied from the MY_CORP network to the DEVELOP network. 
The Delete command removes an object from your network.

Figure 2-12 Cutting A Device 

FIG 
Figure 2-13 Pasted Device 
Adding Map Backgrounds to Your Network 
Map backgrounds can be added to network and subnetwork windows to help you show the physical and logical layout of your network. Enterprise Manager provides a few map backgrounds to give you some ideas about what you can achieve, but you will probably want to create your own based on scanned images of floor plans or city street maps. 
To add a map background to a window: 
1From Options menu, choose Show Tools. 
Enterprise Manager displays the Tools box, as shown in Figure 2-5, in the bottom left corner of the active network or subnetwork window. 
2Move the mouse pointer over the Map tool and double-click. 
Enterprise Manager displays the Map Selection dialog box as shown in Figure 2-14. 
3Select the name of file to be used as a map background. 
4Ensure the Display Background check box has been selected. 

FIG 
Figure 2-14 Map Selection Dialog Box 
In the Map Selection dialog box: 
File Name Provides a list of filenames for the map background. 
List Files of Type Displays a list of the graphics file formats you can use for your map background. Enterprise Manager supports the following file formats: 
·BMP - Window bitmap 
·GIF - Bitmap 
·PCX - Window Paintbrush 
·TGA - Targa bitmap 
·TIF - Tag Image File Format (TIFF) drawing file 
·WMF - Windows Metafile 
Directories Lists the directories available on the current drive. 
Drives Lists the drives available on your system. 
Finding Devices on Your Network 
If you have a large network which you have divided into many subnetworks, you may sometimes forget which subnetwork a particular device is on. You can use the Find command to display the subnetwork that contains the device. 
1From the Data menu, select Find. 
2In the Find dialog box, double-click on an empty Find field. 
Enterprise Manager displays a list of device attributes for which you can search. 
3From the list of device attributes, choose either the device name, the MAC address, the IP address or IPX address. 
4Double-click on the Operator field and choose the equals sign (=). 
5In the Value field, enter the value of the attribute to be searched; for example, the device name PC and Unix, shown in Figure 2-15. 

FIG 
Figure 2-15 Find Dialog Box 
Enterprise Manager displays the Find confirmation box showing the name of the subnetwork on which the device is located and is shown in Figure 2-16.

 3 Working with the Event Log 
This chapter contains the following topics: 
·Displaying the Event Log 
·Using The Event Log 
·Working with Trouble Tickets 
·Printing Reports 
Displaying the Event Log 
The event log lets you view a list of network events. An event is any network or node activity that generates a trap and is sent to Enterprise Manager. If a device fails to respond to a poll request from Enterprise Manager, this is also recorded in the event log. The event log can be displayed in a window with events color-coded to show four levels of severity. You can display the event log for a particular device or for a whole subnetwork. 
When a device has an event that has not been acknowledged, the color of the icon changes to that of the most severe event. The color of the subnetwork to which the device belongs changes color to either the same color as the device, or to a color one level of severity less than the device. For more information about representing device events at the subnetwork level, refer to Changing the Way Events are Reported . 
To display the event log: 
1Select the subnetwork or device. 
2From the Options menu, choose Show Event Log. 
In the Event Log, shown in Figure 3-1, events are described by the following fields: 
Ack Shows whether or not the event has been acknowledged. 
Time Shows the time at which the event was logged by Enterprise Manager. 
Severity Shows the severity level of the event: 
Green Normal. 
Yellow Minor. 
Orange Major. 
Red Critical. 
Generated By Specifies the device which generated the event. In some cases the event is generated by either the device or by Enterprise Manager. For example, the Device Failed message is generated by Enterprise Manager. 

FIG 
Figure 3-1 The Event Log 
Subnetwork Shows the subnetwork address of the device. 
Event Description Gives a brief description of the event. 
WorkGroup PC Links maintains an alarm log for grouping views of PCs. For more information about using the WorkGroup PC Links component, see the Transcend WorkGroup PC Links User Guide. 
Using The Event Log 
As you manage the network, the event log accumulates events, errors, and warnings. If this happens, not only do the events take up disk space, but the event log can become difficult to work with. Old events that have been resolved, but not removed from the event log could cause confusion. 
The color of a node icon shows if there are unacknowledged events regardless of when that event occurred. The object remains that color until the event is acknowledged or deleted, when it changes to the color of the next most severe event. When you have resolved a problem, or are no longer interested in it, either acknowledge the event or delete it. 
The Event Log window menus are described below: 
Ack 
Causes the unacknowledged marker to be removed from selected events in the event log. 
To acknowledge events, select the events you want to acknowledge and select Ack from the menu bar. Enterprise Manager prompts you to confirm if you want to acknowledge the events, as shown in Figure 3-2, and then removes the unacknowledged markers. If you do not select any events and select Ack, all events are acknowledged at once. 

FIG 
Figure 3-2 Ack Menu 
Delete 
Removes the selected events from the event log. 
To delete events, select them and choose Delete. Enterprise Manager prompts you to confirm, shown in Figure 3-3. Click Yes to confirm and remove the events from the log. 

FIG 
Figure 3-3 Del Menu 
NOTE: By default, events are deleted when you acknowledge them. You can change this by choosing Console from the Configure menu and clearing the Delete when acknowledged check box in the Console Configuration dialog box. See Changing the Way Events are Reported for more information. You can also choose Purge Event Log from the Options menu to delete all the events in the event log. 
Find 
This option is grayed out and will be implemented in a future release of Enterprise Manager. 
Print 
Prints the selected events from the event log. 
To print events, select them and choose Print. 
View 
Lets you display the events in Ascending or Descending order. By default events are displayed in Descending order. 
Help 
Provides Help for the Event Log menu options and dialog boxes. 
Working with Trouble Tickets 
Trouble tickets provide you with an easy way to keep track of any responses you need to make to events on your system. You can use trouble tickets to keep a record of who was assigned to deal with an event, and what actions were taken. 
To add a trouble ticket to an event: 
1In the Event Log window, double-click on the event for which you want to add a trouble ticket.1 
Enterprise Manager displays the Event Acknowledgment dialog box, as shown in Figure 3-4. In the Event Acknowledgment dialog box: 

FIG 
Figure 3-4 Event Acknowledgment Dialog Box 
Event Shows the name of the subnetwork and device that generated the event, the severity, and the transport protocol used. 
Description Provides a brief description of the event. 
Detail/Probable Cause Provides a detailed description of the event, and where possible an explanation of the probable cause. 
Trouble Tickets Provides a pull-down list of any existing trouble tickets associated with the event. 
2In the Event Acknowledgment dialog box, click on the Tickets button. 
Enterprise Manager displays the Trouble Ticket dialog box, as shown in Figure 3-5. 
In the Trouble Ticket dialog box: 
Ticket Number Shows the number of the trouble ticket. Enterprise Manager automatically increases this number each time you add a trouble ticket to the event log. 
Assign Person, Description, Detail Provides fields for you to enter the name of the person dealing with the event, more information about the nature of the event, and any action taken. 
Timestamps Provides fields for you to enter details about when the trouble ticket was added, and when the event was dealt with. 

FIG 
Figure 3-5 Trouble Ticket Dialog Box 
3In the Trouble Ticket dialog box, enter the appropriate information in the fields provided. 
Once an event has been dealt with, you can then double-click on the appropriate ticket in the Trouble Tickets pull-down menu. You can modify the ticket to record any action taken, or delete the trouble ticket. To modify a ticket, make your text changes and click Modify. To delete a trouble ticket, click on Delete. 
Printing Reports 
Enterprise Manager enables you to print four types of report: Event Log lists the events that have occurred on the network, Device Addresses lists the names of devices found by Autodiscovery and their IP addresses, Trouble Tickets list the trouble tickets created in the event log, and Connections lists the connections on your network. These reports have many uses. For example, you can obtain a printed inventory of equipment on your network, monitor the overall performance of devices and keep control of trouble tickets. 
To choose and print a report: 
1From the Data menu, choose Report. 
The Print Report dialog box is displayed, shown in Figure 3-6. 
2Select the report you want to print. 
3Select whether the report is sent to a printer, displayed in a window, or saved in a file. 
4If required, click Selection Criteria and use the Selection Criteria dialog box to ensure that only the appropriate information is reported. 
5Click Print. 

FIG

 4 Changing the Enterprise Manager Setup 
This chapter contains the following topics: 
·Changing the Console Settings 
·Changing the Way Events are Reported 
·Configuring a Statistics Display 
·Adding New Users 
·Changing and Deleting Users 
·Starting Other Applications 
·Setting Preferences 
Changing the Console Settings 
Enterprise Manager enables you to change the parameters that control how it communicates with devices on your network; you may want to do this if Autodiscovery does not find devices you know to be active on the network. You can also limit the size of the event log to prevent it using too much disk space. You can make these changes by displaying the Console Configuration dialog box: 
1From the Configure menu, choose Console. 
2In the Console group, make any changes you consider necessary to improve the performance of Enterprise Manager on your network. 
In the Console Configuration dialog box, shown in Figure 4-1: 
Name Displays the name of the network. 
Log File Name Displays the name of the file used to store data from the event log. 
Log File Size Allows you to determine the maximum number of events in the event log. The values you can set are between 100 to 9999 events. The default size is 1024 events. As you manage the network, the event log accumulates events, errors and warnings which take up disk space. You can limit this disk space by typing the maximum number of events in the Log File Size box. When the event log is full, it is overwritten from the beginning of the file and the oldest events are deleted. 
SNMP Community Name Displays the default community string used to communicate with devices on the network. 
Polling Interval Displays the frequency in seconds at which Enterprise Manager checks devices on the network to find out if they are still communicating. Set the polling interval to be frequent enough to gather data, but not so frequent that it slows Enterprise Manager or your network down. The default polling interval is 10 seconds. 
For example, 120 seconds is almost certainly too long an interval as a lot can happen on a network in this time whereas 1 second is too short an interval as the large number of polling responses could not be handled. 

FIG 
Figure 4-1 Console Configuration Dialog Box 
Timeout Displays the time in milli-seconds that Enterprise Manager waits for a device to respond to a poll request before it assumes the request has failed. Time-out can be set at values between 0 and 9999ms. The default time-out is 350ms. 
Number of Retries Displays the number of times Enterprise Manager requests a response from a device before assuming the device is not communicating. Number of Retries can be set at values between 0 and 99. The default is 2. 
The time-out and number of retries affect how long Autodiscovery takes to find devices on your network. Increasing these values can increase the accuracy of Autodiscovery and prevent inaccurate No Response messages to the event log, but it increases the time it takes Autodiscovery to run. 
Transport Protocol Sets the network transport layer protocol that Enterprise Manager uses to communicate with devices. If you select IPX, Autodiscovery finds devices that use IPX. However, detailed management is not available for all devices. 
Changing the Way Events are Reported 
Enterprise Manager enables you to change the way events are reported to you and displayed on your network. You can make these changes by displaying the Console Configuration dialog box: 
1From the Configure menu, choose Console. 
2In the Events group, click on the appropriate buttons to turn on or off audible warnings, and if required, click in the check boxes for decrement severity level and delete events when they are acknowledged. 
In the Events Panel of the Console Configuration dialog box, shown in Figure 4-2: 
No Response (Audible/Not Audible) Determines whether your PC beeps when Enterprise Manager receives a warning that a device is not responding. 
Critical (Audible/Not Audible) Determines whether your PC beeps when Enterprise Manager receives a warning of a critical event. 
Major (Audible/Not Audible) Determines whether your PC beeps when Enterprise Manager receives a warning of a major event. 
Minor (Audible/Not Audible) Determines whether your PC beeps when Enterprise Manager receives a warning of a minor event. 
Decrement severity at each sublevel Selects whether or not the color of a subnetwork icon is lowered by one level of severity from the subnetwork's most severe unresolved event. For example, if decrement severity is selected and a stack in the subnetwork generates a warning for a critical event, the device icon turns red but the subnetwork icon to which it belongs turns orange. 
Delete when acknowledged Selects whether or not events in the event log are automatically deleted when you acknowledge them. This is useful if you do not need to keep acknowledged events in the event log. 

FIG 
Figure 4-2 Event Report Configuration 
Configuring a Statistics Display 
You can control the way Enterprise Manager displays windows containing graphs and charts. 
To change a statistics display: 
1Select the window you want to configure. 
2From the Configure menu, choose Active Display Window. 
Enterprise Manager displays the Active Display Configuration dialog box as shown in Figure 4-3. 

FIG

FIG 
Figure 4-4 Font Dialog Box 
Defaults Returns all the fields to their default values. 
Adding New Users 
To prevent unauthorized access to your network, Enterprise Manager uses a system of user names, passwords, and access levels. When you install Enterprise Manager, it creates one user, called admin, with no password and with access to all of the Enterprise Manager features. 
If you have more than one person who needs to use Enterprise Manager, you add users, and to increase security you can assign a password and set their access level. Depending on a user's access level, certain commands or options appear grayed out. 

FIG 
Figure 4-5 Console Configuration Dialog Box 
Enterprise Manager enables you to select one of three access levels for a user: 
Read/Only The user can only view and monitor a network, but is unable to make changes to, or perform any configuration of Enterprise Manager. 
Read/Write The user can monitor a network and make changes to it, but is unable to make changes to, or perform any configuration of Enterprise Manager. 
Administration The user can access all the Enterprise Manager commands to configure and change Enterprise Manager. 
To add a new user for Enterprise Manager: 
1In the Configure menu, click Console. 
2In the Users group, click ADD NEW USER. 
Enterprise Manager displays the Add Console User dialog box, as shown in Figure 4-6. 
3Enter the name and password (if required) for the new user.

To change or delete the details of a Enterprise Manager user: 
1From the Configure menu, choose Console. 
2In the Users group, double-click on the user name you want to change or delete. 
Enterprise Manager displays the Change/Delete Console User dialog box, as shown in Figure 4-7. 
3To change the user's password, click Password. In the Change Password dialog box, enter the old password followed by the new password. 
4To change the user's access level, select either Read/Only, Read/Write, or Administrator in the User Access group. 
5Continue as follows: 
·To confirm any changes to the user's password, notification, or access level, click on Done. 
·To cancel any changes to the user's password, notification, or access level, click on Cancel. 
·To delete a user, click Delete. Enterprise Manager asks you to confirm your action before deleting the user and returning you to the Console Configuration dialog box. 
NOTE: The Notification button in the Change/Delete Console User dialog box is not supported in this release of Enterprise Manager and is grayed out. 

FIG 
Figure 4-7 Change / Delete Console User Dialog Box 
Starting Other Applications 
Enterprise Manager allows you to create a new menu, called Programs, to which you can add items which start other applications. You might want to do this so that you can easily start a spreadsheet or word processor application or send electronic mail to network users while you are using Enterprise Manager. 
To add a new application to the Programs menu: 
1From the Configure menu, choose Menu. 
Enterprise Manager displays the Menu Configuration dialog box, as shown in Figure 4-8.

 A Getting Started with Internetworking 
This appendix contains the following topics: 
·The Origins of TCP/IP 
·TCP/IP Architecture 
·Internet Addressing 
·Internet Address Classes 
·Introduction to Subnets 
·Introduction to Novell NetWare 
·IPX Addressing 
The Origins of TCP/IP 
The Transmission Control Protocol/Internet Protocol (TCP/IP) is the common name applied to a family of data communication protocols used to connect computers and data communications equipment into computer networks. It is used on a large international network called the Internet, which is composed of universities, government facilities, research institutions and private companies. The Internet system can be viewed as a collection of hosts and networks interconnected by IP routers. Routers are specialized computers that connect two or more networks and pass traffic between them. 
TCP/IP is also found on Local Area Networks (LANs) composed of many different types of computers, and on networks connecting engineering workstations. The list below provides a summary of the development of TCP/IP. 
TCP/IP Defined: 
·Common name for a family of data communication protocols. 
·Used on an international network called the Internet. 
·Also used on LANs. 
History: 
·Developed for US DoD in the early 1970's. 
·Included in Berkeley's UNIX Version 4.2 in early 1980's. 
Growing Popularity: 
·Vendor Independence. 
·Used on machines of all sizes. 
·De facto standard for workstation communications. 
The strength of TCP/IP is that it provides connectivity between equipment from many vendors over a wide variety of networking technologies. It consists of a well defined set of communications protocols and several standardized application protocols. Included within TCP/IP is the application protocol which supports network management. Enterprise Manager and WorkGroup Manager use this protocol to gather information from other devices using TCP/IP on the network. 
The TCP/IP communication protocols were originally developed in the early 1970's for the US Department of Defense as an experimental, packet-switched, wide area network (WAN). The experiment was very successful and has resulted in the TCP/IP protocol stack being further expanded and refined over the years. These same protocols were later adapted for use on LANs to provide wide area access. 
In the early 1980's, TCP/IP was included as an integral part of Berkeley's UNIX Version 4.2. The proliferation of UNIX 4.2-based workstations in computer-aided design, manufacturing, and engineering environments made TCP/IP the de facto standard for workstation communications. 
TCP/IP Architecture 
TCP/IP is a set of protocols divided into four layers, as shown in Figure A-1. A typical TCP/IP application, such as Enterprise Manager or WorkGroup Manager, uses all four layers when communicating across a network. 
Application layer protocols send or receive a sequence of messages or stream of bytes. Enterprise Manager and WorkGroup Manager use the Telnet remote terminal access protocol and the Simple Network Management Protocol (SNMP). Telnet provides a way of remotely accessing the local management of a device or host. SNMP defines the format for the management data and the type of exchanges that may take place between Enterprise Manager or WorkGroup Manager and the other devices on the network. 
Transport layer protocols provide the reliable communications services needed by the applications layer. The User Datagram Protocol (UDP) provides a simple transaction service with a minimum of protocol overhead. The Transmission Control Protocol (TCP) offers a reliable delivery service for applications that require guaranteed delivery. 
Internet layer protocols provide the basic service of delivering blocks of data (datagrams) to their final destination across multiple networks. Each IP datagram carries the Internet address of the ultimate destination. This destination address is used by the routers on the Internet to make routing decisions as they forward the datagram to its final destination. Each IP datagram also carries the Internet address of the original source. The source address is used by the routers to inform the source station if the datagram encounters errors as it is routed through the Internet. The Address Resolution Protocol (ARP) maps Internet addresses onto physical addresses (Ethernet, Token Ring or FDDI). The Internet Control Message Protocol (ICMP) provides advice and error messages about conditions on the network. 
Network Interface layer protocols define the rules that determine how a host accesses local area networks. The protocols define how a host connects to the network, not how the actual network works.

Internet Addressing 
A world-wide communications system needs a globally-accepted method of identifying individual computers. Devices (or hosts) on the Internet are assigned unique addresses. The Internet then behaves like a virtual network, using these assigned addresses when sending or receiving packets. 
Internet addressing uses a 32-bit (or 4 octet) address field. The bits that make up an Internet address are divided into two parts: 
·The first part identifies the network on which the host resides. 
·The second part identifies the host itself. 
Hosts attached to the same network must have the same number assigned to the network portion of the address, but will have different numbers assigned to the host portion of the address. 
To ensure the uniqueness of Internet addresses, they are assigned by the Network Information Center (NIC). This organization assigns a globally unique network number to each network that wants to connect to the Internet. The NIC only assigns the network portion of the address; assigning unique host numbers is your responsibility. 
If you do not plan to be connected to the Internet but need to use TCP/IP protocols, you could assign network addresses on your own. However, NIC will assign and register unique Internet addresses to organizations not planning to join the Internet, and if you do decide to join the Internet later you will have avoided any potential addressing conflicts. 
To make Internet addressing easier to understand, IP addresses are usually written in dotted decimal notation, as shown in Figure A-2. When using decimal notation, the values of the four octets are written in the standard decimal format, separated by decimal points. 
Depending on the Class (or type) of the Internet address, there are many ways that the 32-bit Internet address field can be divided into a network number and a host number. The method used to convey how an Internet address is divided is determined by the most significant bits in the 32-bit address field.

Internet Address Classes 
There are four classes of Internet addresses. Each address class begins with a unique bit pattern, which is used by the Internet software residing on network hosts to identify the address class. 
Once the Internet software has identified the address class, it can determine which bits are used to represent the network number and which bits are used to identify the host portion of the address. Figure A-3 shows examples of Internet addresses. 
A Class A network address has the highest order bit set to 0, a seven-bit network number and a 24-bit host address. 125 Class A networks can be defined with up to 16,777,214 hosts per network. Class A addresses are in the range 001.xxx.xxx.xxx to 126.xxx.xxx.xxx, where xxx represents the host portion of the address 
A Class B network address has the two highest order bits set to 1-0, a 14-bit network number, and a 16-bit host address. 16382 Class B networks can be defined with up to 65,534 hosts per network. Class B addresses are in the range 128.001.xxx.xxx to 191.254.xxx.xxx. 
A Class C network address has the three highest order bits set to 1-1-0, a 21-bit network number, and an 8-bit host address. 2,097,152 Class C networks can be defined with up to 254 host per network. Class C addresses are in the range 192.000.001.xxx to 223.255.254.xxx 
A Class D network address is used as a multicast address. The four highest order bits are set to 1-1-1-0. Multicasting is used to send an IP datagram to all members of a "host group" A host group is composed of a set of hosts identified by a single IP address. Class D addresses are in the range 224.000.000.000 to 239.255.255.255. 

FIG 
Figure A-3 Internet Address Classes 
Introduction to Subnets 
You can configure more than one IP network (or subnet) on a single physical network. Support for multiple logical networks on a single physical network is important because the number of bits assigned to the host portion of an Internet address limits the number of hosts that may be addressed on any given IP network. 
If the physical medium can support many more hosts than there are Internet addresses, this can become a constraint on your network. This problem could easily appear when attempting to implement Class C addressing. The solution is to assign another network number to the same media, thereby doubling the number of addresses that may be assigned. 
Subnetting can also be used to solve the problem that occurs if you have been assigned only one network number from the Internet, but you have multiple physical networks. If you have been assigned a Class B Internet address, but you have three separate physical networks, you can use routers to connect the physical networks, but make them appear as a single network to Internet routers outside the system. 
In the example in Figure A-4, a site with three physical networks uses subnet addressing to cover them with single Class B network address. The router to the Internet accepts all traffic for the network 128.005.000.000, and chooses the physical network bases on the third octet of the address. 
This adds another level of hierarchy to the IP addressing structure; instead of a two-level (network, host) structure, a three-level (network, subnetwork, host) structure has been created. 
Subnet masks enable the host portion of an Internet address to be divided into two parts: 
·The first part identifies the subnet number 
·The second part identifies the host on that subnet 

FIG 
Figure A-4 Subnets and Subnet Masks 
The bits of the subnet mask are set to 1 if the device should treat the corresponding bit in the Internet address as part of the original network number or as part of the subnet number. These bits in the mask are set to 0 if the device should treat the bit as part of the subnet host number, as shown in Figure A-4. 
Introduction to Novell NetWare 
Novell NetWare is a network operating system that co-ordinates the operations of many computers, allowing many users to gain access to the network's services. From a workstation, a user can map drive letters to remote subdirectories on a NetWare server, or map a local printer to a server's print queue. NetWare also provides a set of administrative tools for creating and deleting user accounts, managing file access for those accounts, and managing print queues. 
NetWare consists of two basic components, as shown in Figure A-5: 
·NetWare Shell 
·IPX/SPX interface 
The NetWare shell monitors DOS calls from applications executing on the workstation and determines whether the DOS calls are bound for the local workstation or if they should be redirected to a remote device on the network. 
The Internet Packet Exchange/Sequenced Packet Exchange (IPX/SPX) interface allows the processes on the workstation or server to communicate with other devices on the network. IPX provides the typical OSI Network Level functions of addressing, routing, and switching of packets from the source workstation to the destination. The implementation of a reliable delivery service can be built upon the services of IPX through the use of SPX. 
NetWare enables the services and resources residing on one network to be made available to workstations on other networks. Netware uses IPX routers to connect networks together and pass traffic between them. If two workstations on different networks want to communicate, the source station sends the packets to the appropriate IPX router. The router forwards each packet through the system of routers and networks until it reaches a router connected to the same network as the destination node. The final router transmits the packet to the physical address of the destination node. 

FIG 
Figure A-5 IPX Architecture 
NetWare and TCP/IP can be installed on the same device, enabling it to communicate with other devices using either IPX or IP as appropriate. For example, Enterprise Manager and WorkGroup Manager include the TCP/IP protocols and if you install either of these on a PC which is also running NetWare, Enterprise Manager or WorkGroup Manager will try to communicate with devices using first IP, and then, if there is no response, IPX. 
IPX Addressing 
The IPX addressing scheme provides consistent addressing across networks connected together using IPX routers. A complete IPX network address is made up of three fields, as shown in Figure A-6: 
·Network number 
·Host number 
·Socket number 
The network number is a 32-bit (4-byte or 8 hex digits) number that uniquely identifies a single network in an IPX internet. This portion of the address is preceded by an ampersand (&) and is generally assigned by the network administrator. A fundamental assumption for routing in an IPX environment is that the internet contains at most a few hundred networks. As a result, the network number space is flat and all IPX routers will contain a complete image of the IPX internet in their routing tables. 
The host number is a 48-bit (6-byte or 12 hex digits) number that uniquely identifies a host. This portion of the address is preceded by a percent sign (%) and will be the Ethernet address of the host. 
The socket number is a 16-bit (2-byte or 4 hex digits) number that uniquely identifies a socket within the operating system of the host. A socket is a queue used to send and receive interprocess communications. This portion of the address is preceded by an exclamation mark (!).

B 3Com On-line Documentation 
This appendix contains the following topics: 
·Why Use On-line Documentation? 
·3Com's On-line Documentation 
·Starting the Viewer 
·Viewing Documents 
·Viewing Pictures 
·Moving Around Using the Document Outline 
·Moving to Chapters Referenced by the Current Chapter 
·Moving to Chapters Which Reference the Current Chapter 
·Returning to a Previous Document or Chapter 
·Finding Specific Information 
·Making and Displaying Notes 
·Making and Finding Bookmarks

·Configuring the Viewer 
Why Use On-line Documentation? 
There are several advantages to using on-line documentation: 
·You always know where the documents are stored. The documents are always on the computer and they cannot be taken away under normal circumstances. This is unlike paper documents which can be moved or lost. 
·You can read on-line documents at the same time as other users. You do not need to buy extra documents, just allow more people to access the on-line documentation. 
·You can search on-line documents for particular words or topics at great speed, enabling you to access information quickly. 
3Com's On-line Documentation 
Enterprise Manager is supplied with a compact disc (CD-ROM). In addition to the Enterprise Manager software, the CD-ROM contains: 
·The manuals for Enterprise Manager, the devices managed by Enterprise Manager, and a variety of other 3Com products. 
·An on-line viewer called the KnowledgeSet Retrieval System for Windows (KRSWIN), which allows these documents to be viewed on a PC. 
If you have a PC as described in Keeping Earlier Versions of On-line Documentation on page B-3, you can use this CD-ROM as an on-line documentation system. 
Keeping Earlier Versions of On-line Documentation 
The on-line documentation supplied with Enterprise Manager version 4.1 replaces the on-line documentation provided with earlier releases of this product. You should delete the Enterprise Manager version 3.x on-line documentation program group and program icons before you install the Enterprise Manager version 4.1 on-line documentation. 
If you need to access the earlier versions of the on-line documentation (for example, if you have added useful bookmarks or notes to version 2.x books), you should install the version 4.1 on-line documentation in a different directory to the version 3.x on-line documentation. When the installation is complete, you should add any version 3.x books you want to access to the version 4.1 library. To add a version 3.x book to the version 4.1 library, use the Install Books command from the File menu. 
Starting the Viewer 
To start the Viewer, double-click on the Viewer application icon in Program Manager. The Viewer Start-up window is then displayed, as shown in Figure B-1.

·A Document window - where the selected documents are displayed 
Exiting From the Viewer 
When you have finished using the Viewer, you can exit by selecting Exit from the File menu. 
Viewing Documents 
As shown in Figure B-2, the Navigation window initially contains the Library List; a list of the on-line document libraries you have installed. Each entry in this list is colored magenta and surrounded by a box; this indicates that the entry is a hotlink. In the Navigation window, you use hotlinks to access libraries and navigate your way around them. If you click on a hotlink here, the contents of a library is displayed. 
Hotlinks are also used in the Document window to jump to text cross-referenced by the current text. 
To view a document: 
1Click on a library in the Library List. 
The Viewer displays the Book List for the library; a list of the book databases in the library. 
2Click on a book database. 
The Viewer displays a list of the book titles in the book database. 
If the library is large, then further book categories may appear rather than book titles. To display the book titles in a category, click on the appropriate book category. 
3Click on a book title. 
The Viewer displays the table of contents for the document in the Document window. 
4Click on a heading in the table of contents to display the appropriate section of the document. 
If a document does not have a contents page, then the start of the document will be displayed automatically. 
When the appropriate section of the document is displayed, you can: 
·Scroll through the section using the scroll bars at the side of the Document window. 
·Move around the section or move to another section in the document by using hotlinks in the text. 
·Return to the table of contents by selecting Table of Contents from the View menu. 
·View the contents of the current book database or another book database by returning to the Book List, and clicking on a title. 
If the Navigation window does not contain the Book List, you can display it by selecting the Book List option from the View menu. 
·View the contents of another library by returning to the Library List, and clicking on another library title. 
If the Navigation window does not contain the Library List, you can display it by selecting the Library List option from the View menu. 
Viewing Pictures 
When you click on a FIG hotlink in the Document window, the Viewer displays pictures in a Figure window as shown in Figure B-3. 

FIG 
Figure B-3 Displaying the Figure Window 
Leaving the Figure Window Open 
You can leave the Figure window open when you are viewing documents. Each time you click on a new FIG hotlink, the new picture is displayed, replacing the previous picture in the window. 
You can display the next or previous picture by selecting the Graphics menu and choosing Show Next Image and Show Previous Image respectively. 
Altering the Size of a Picture 
You can alter the size of each picture to display more or less detail. To do this, you use the Zoom In, Zoom Out and Full Scale options on the Graphics menu. 
Viewing Pictures In Line With The Text 
Rather than clicking on FIG hotlinks to display pictures, you can display pictures in line with the text. To do this, take the following steps: 
1From the Options menu, choose Preferences. 
The Preferences dialog box appears as shown in Figure B-4. 

FIG 
Figure B-4 The Preferences Dialog Box
