3Com (R) Corporation LAN Installation Disk
for the 3Com Megahertz LAN PC Card Family
Troubleshooting Information
If the LAN PC Card diagnostic tests fail,
the PC Card may not be defective.
Check the following:
1. Make sure that the PC Card is operating in a notebook
containing the PC Card standard Type II or Type III slots.
2. Make sure that the PC Card is completely seated in its
slot. Review the installation instructions in the
User Guide.
3. Make sure that your notebook is running DOS 3.1 or
higher and that no device drivers or memory managers are
loaded.
4. Inspect all cables and connections.
5. If you are running the Echo Exchange test, make sure
that the LAN PC Card is securely connected
to a properly cabled network and an echo server is set up
on the network.
6. If you are configuring the I/O base address or interrupt
request level make sure that the settings you select for
these parameters do not conflict with any other peripheral
or software program installed in the computer. If your
notebook has Card Services, these parameters are set
automatically, and you cannot change them.
7. The notebook may be defective. Install the PC Card in a
known functioning notebook and run the tests again.
8. Replace the failed LAN PC Card with a
known working PC Card, with the same configuration. If
the second PC Card fails, something is probably wrong
with the test environment, not with the PC Card.
9. Try the PC Card in another slot.
