3. If there is more than one adapter installed in your computer, a selection menu
displays each adapter by its universally administered address. Use the cursor
keys or the mouse to select the adapter to test.
4. Connect the adapter to the network and press the Enter key to select Test.
There are two test options: wrap test and on-ring test.
v The wrap test tests the adapter and cable through the hub or concentrator, or
through a wrap plug attached to the cable.
v For the on-ring test, the adapter must be connected to a network with other
adapters, so the ring speed of the network can be automatically sensed. If
the adapter is the only one in the network, the on-ring test will fail.
5. Select the option for the test to perform.
6. If the test indicates that there is no adapter in the system, or that diagnostics
cannot be run:
v Check that the adapter is correctly seated in the slot.
v Make sure that the LEDs blink alternately amber and green after you power
up your computer.
v See Table 5 on page 44 for LED states.
v Run the adapter diagnostics again. If the tests are completed successfully,
and your computer still is not communicating, contact your network
administrator.
7. If the wrap test and on-ring test run without errors, the adapter is ready for use.
Exit the diagnostic program, and follow the directions for reactivating the
computer.
If an error occurs, record any messages that appear, record the LED
sequences, and contact your network administrator.
Note: This procedure does not verify that the data rate of the device driver
setting matches the data rate of the LAN segment.
Understanding the adapter LEDs and labels
Figure 2 on page 44 and Table 5 on page 44 describe the LEDs and labels located
on the bracket of the adapter.
