 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.  If you are configuring the I/O base address, interrupt request level, or
     boot PROM base address, make sure that the settings you choose for these
     parameters do not conflict with any other peripheral or software program
     installed in the computer.  For a list of system resources commonly used
     by other peripherals, select "Commonly used interrupt and I/O base 
     addresses" from the "Configuration and Diagnostic" submenu.

 5.  Make sure that the configuration setting for the transceiver type is

 6.  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.

 7.  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.

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

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

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

 11. 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.
