DIAGNOSTIC TESTS

This chapter explains how to isolate and solve 10/100BASE-T4 PCI adapter problems.

Make sure that the adapter is correctly installed. (See Chapter 2 for installation instructions.)

This chapter contains information about the following topics:

■Diagnostic tests overview

■Starting the diagnostic program

■Getting help if a test fails

■Changing the test setup

■Miscellaneous checks

The 3Com diagnostic program is a DOS program. If you are running an operating system or interface other than DOS, refer to the section “Accessing DOS” in Chapter 3.

Troubleshooting with the Diagnostic Tests

The diagnostic tests on the 3C59X EtherDisk diskette check the adapter’s overall operation and permit the isolation of faults. You can run the diagnostic tests after installing the 10/100BASE-T4 PCI adapter, 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.
