SUMMARY
When you are have problems installing 3com Etherdisk drivers for
Etherlink and the Etherlink III (R) Bus Master Adapters, the
troubleshooting guide below will help you with a smooth installation.
If the adapter diagnostic tests fail, the adapter might not be defective.
Check the following:
- Make sure the adapter is completely seated in its slot. Review
the installation instructions in the appropriate adapter guide.
- If you are running the Group 2 test, make sure the adapter is securely
connected to a loopback plug or to a properly cabled network.
- If you are running the Group 3 test, make sure the adapter is
securely connected to a properly cabled network and an echo server is
set up on the network.
- Make sure the configuration setting for the transceiver type is
correct.
- Running Group 2 tests while connected to an active network can cause
intermittent failures. These failures can be avoided by using a
loopback plug or by connecting to an inactive network on which only
the computer being tested is operating.
- If you installed a twisted-pair adapter, check the LED on the
back plate of the adapter. The LED should be checked only during or
after the diagnostic tests have been run. The LED will be on when
there is a correct connection between the adapter and the hub. The
LED will flash if the polarity of the connection is swapped.
- Install the adapter in another slot and run the tests again. The slot
in the computer may be defective.
- Install the adapter in a known, functioning computer and run the tests
again. The computer in which the adapter is installed might be
defective.
- Try a different loopback plug. The loopback plug you are using might be
defective.
- Replace the failed adapter with a known working adapter with the same
configuration. If the second adapter fails, something is probably
wrong with the test environment, not with the adapter.
