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.
