 If the adapter diagnostic tests fail, the adapter might not be defective.
 Check the following:

 1.  Make sure that the adapter is completely seated in its slot.  Review
     the installation instructions in the appropriate adapter guide.

 2.  If you are running the Group 2 test, make sure that the adapter is
     securely connected to a loopback plug or to a properly cabled network.

 3.  If you are running the Group 3 test, make sure that the adapter is
     securely connected to a properly cabled network and an echo server is
     set up on the network.

 4.  Make sure that the configuration setting for the transceiver type is
     correct.

 5.  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.

 6.  If you installed a twisted-pair adapter, check the LED on the 
     backplate 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.

 7.  The slot in the computer may be defective.  Install the adapter in
     another slot and run the tests again.

 8.  The computer in which the adapter is installed might be defective.
     Install the adapter in a known functioning computer and run the tests
     again.

 9.  The loopback plug you are using might be defective.  Try a different
     loopback plug.

 10. 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.
