Locating the Network Drivers

The 3C59X EtherDisk diskette contains the latest versions of the network drivers available when 3Com shipped the adapter.

It also contains other important information concerning the

3C592 EISA adapter.

The drivers on the 3C59X EtherDisk diskette (3C59X drivers)

are compatible with the following bus master adapters:

Fast EtherLink EISA 10/100BASE-T (3C597) adapters,

Fast EtherLink PCI 10/100BASE-T (3C595) adapters,

EtherLink III EISA 10 Mbps (3C592) adapters, and EtherLink III

PCI 10 Mbps (3C590) adapters. The 3C59X drivers are not backward-compatible with the 3C5X9 family of EtherLink III adapters (ISA, EISA, or MCA). The latest version of the

EtherDisk diskette is available on 3Com’s Bulletin Board

Service (BBS). For information on accessing the BBS, refer to

Appendix B, Technical Support.”

To obtain NOS drivers not included on the 3C59X EtherDisk diskette, access Document 9071 in 3Com’s 3ComFacts

fax service. Document 9071 provides a list of available drivers and drivers in development along with information on where these drivers can be obtained.

Accessing DOS

The 3Com program for installing drivers is a DOS-based program that loads network drivers, modifies some adapter parameters, and runs diagnostic tests on the adapter. If you are using an operating interface other than DOS, such as

OS/2

, Windows 3.x, or Windows 95, you must exit from that interface before installing the drivers. Table 4-1 describes how to access DOS from various operating systems.

One adapter in a client

Multiple adapters in a client

One adapter in a server

Multiple adapters in a server

One Adapter in a Client

To load the driver for a single adapter in a NetWare DOS ODI environment, follow the instructions in this section. The

3Com DOS ODI driver is 3C59X.COM.

3Com’s AutoLink auto installation software automatically installs all necessary NetWare DOS ODI client software, including drivers. The software also modifies the CONFIG.SYS and AUTOEXEC.BAT files. It automatically logs on to the server and updates the client software if your system administrator has already configured a 3Install account on your server.

Instructions for configuring a 3Install account are

RIVERS contained in the README.TXT file located in the

\QINSTALL\SERVER directory on the 3C59X EtherDisk diskette.

If no 3Install account exists, the drivers will be loaded from the diskette (rather than from the server). In this case, they may not be the most current versions.

DOS ODI client drivers that support the 3Com EISA adapter support shared interrupts. However, since there is no industry standard to support shared interrupts, other adapters may support them differently, or not at all. If another EISA adapter does not support shared interrupts, contact its manufacturer for a shared interrupt driver.

AutoLink Requirements

To use the AutoLink feature to install the NetWare DOS ODI driver, your computer must meet the following requirements:

Use the Novell NetWare 2.x, 3.1x, or 4.x network operating system

Have only one 3C592 EISA adapter installed

Be intended for use as a NetWare DOS ODI client

If this does not describe your network environment, refer to the appropriate section later in this chapter.

AutoLink Installation

To use the AutoLink program to install NetWare DOS ODI client software on a PC with a single adapter, complete the following steps.

You can use the AUTOLINK.CFG file to modify the AutoLink process. The AUTOLINK.CFG file in the root directory contains default settings and descriptions of other control parameters.

1 Make sure that you have booted the computer under DOS, version 3.1 or later, and that your computer is connected to the network (refer to Chapter 2).

Troubleshooting with the Diagnostic Tests

The diagnostic tests on the 3C59X EtherDisk diskette check the adapter’s operation and permit the isolation of faults. You can run the diagnostic tests after installing one or more

3C592 EISA adapters, or when a fault is suspected. If the tests in their default configuration do not isolate the problem, you can change the test parameters to meet specific situations.

When the DOS operating system first loads, it executes the

AUTOEXEC.BAT and CONFIG.SYS files. These files are user-definable files that set up the computer environment.

They may also load memory managers and drivers into memory.

Always run diagnostic tests with no device drivers or memory managers (EMM386.EXE and HIMEM.SYS) installed. To avoid loading the drivers or memory managers, you can bypass the

AUTOEXEC.BAT and CONFIG.SYS files. If you are running

under DOS 6.2, pressing [F5] while starting the computer will bypass these two files. If you are using DOS 6.x in a plain DOS

environment, you can bypass the CONFIG.SYS and

AUTOEXEC.BAT files by holding down the right [Shift] key

while starting the computer. If you are using an earlier version of DOS, you must boot from a DOS diskette.

The diagnostic tests are divided into three groups, designated Group 1, Group 2, and Group 3.

Group 1 tests check the physical components and circuitry on the adapter.

The Group 2 test (for the 3C592-COMBO adapter only, not the

3C592-TPO adapter) checks the adapter’s ability to transmit and receive data via the internal transceiver.

The Group 3 test (the Echo Exchange Test) tests the adapter’s ability to transmit and receive data while on the network.

Starting the Diagnostic Program

Running the Group 2 Test

The Group 2 test is called the Network Loopback Test. It tests the 3C592-COMBO adapter’s ability to transmit and receive data via the internal transceiver. This test requires installation of a loopback plug at the adapter’s BNC transceiver connection.

Or, you can run the test on a nonproduction network on which only the computer being tested is operating.

CAUTION: Running the Group 2 test while connected to an

active network can cause intermittent failures.

Assembling a Loopback Plug

If you do not have a loopback plug, you may be able to get one from your authorized network supplier, or you can make your own. To assemble the loopback plug, connect two

50-ohm network cable terminators to a T connector, as shown in Figure 5-2. You can purchase the terminators from your network supplier (3Com part number 3C535).

Miscellaneous Checks

Check for specific hardware problems, such as broken traces or loose and/or broken solder connections.

If you have installed the adapter correctly and you still experience problems, check the software.

Make sure that you have installed the correct drivers for the network operating system you are running (refer to

Chapter 4, “Loading Network Drivers”).

If any problem persists, refer to Appendix B, “Technical

Support.”

Link Beat LED

The 3C592 EISA adapters have an LED for the link beat (see

Figure 1-1). The link beat LED confirms that there is an active connection between the adapter and the hub.

When you first install the adapter and power up the computer, the LED lights, but the link beat is inactive. For the link beat to be active (enabled), you need to have run the

Group 3 test or have loaded the network drivers.

If you are experiencing any problems, first make sure that your hub complies with the 10BASE-T specifications and then check the LED. The meaning of LED activity is given below:

If the LED is on, the link beat is working.

If the LED is off, the link beat has not been established or there is a problem with the connection between the adapter and the hub.

If the LED is blinking, the cable polarity is reversed.
