This index supports xSeries 365 servers.

The symptom-to-FRU index lists symptoms, errors, and the possible causes. The

most likely cause is listed first. Use this Symptom-to-FRU index to help you decide

which FRUs to have available when servicing the computer.

Notes:

1. Check the configuration before you replace a FRU. Configuration problems can

cause false errors and symptoms.

2. For IBM devices not supported by this index, refer to the manual for that device.

3. Always start with “General checkout” on page 15.

4. Take the action (or replace the FRU) suggested first in the list of the right

column, then restart the server to see if the problem has been corrected before

taking further action.

5. Try reseating a suspected component or reconnecting a cable before replacing

the component.

POST error codes and messages are displayed on the screen.
