WINDOWS 3.X

6 TROUBLESHOOTING

This chapter explains how to isolate and solve problems that may occur when you install the 3C509B NIC in a PC running DOS, Windows 3.1, or Windows for Workgroups.

Checklist

If you experience problems installing the NIC, first check these items:

■Check the NIC LED, as described in “Link LED” in Chapter 1.

■Check the connectors. Examine the cable for obvious signs of damage, wear, or crimping. Substitute a known working cable.

■Check whether the NIC software is correctly installed. See Chapter 4.

■Make sure the drivers installed are correct for the network operating system you are running (see “Installing Other Supported Network Drivers” in Chapter 4).

If the problem persists, go to related procedures in this chapter or refer to Appendix D, “Technical Support.”

Diagnostic Testing Under Windows 3.x

The Configuration and Diagnostic Program, on EtherDisk diskette 2, includes the diagnostic program used for DOS, Windows 3.x, and Windows for Workgroups. Run the diagnostic tests after installing the 3C509B NIC to check overall NIC operation and to isolate failures. After the NIC is installed, if the default tests do not isolate the problem, tailor the test parameters to accommodate your specific situation.

Do not run diagnostic tests with device drivers or memory managers installed.

Boot your PC to DOS to avoid installing device drivers or memory managers.
