Troubleshooting

If the PC card diagnostic tests fail, the PC Card may
not be defective.

Check the following:

1. Make sure that the LAN card is installed in a
   standard Type II or Type III slot.

2. Make sure that the PC Card is completely seated in
   its slot. Review the installation instructions in
   the user documentation.

3. Make sure that your computer 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 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 computer has
   Card Services, these parameters are set
   automatically, and you cannot change them.

7. The computer in which the PC card is installed may
   be defective.  Install the PC Card in a known
   functioning computer and run the tests again.

8. Replace the failed 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.
