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 server. 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 37. 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. © Copyright IBM Corp. 2003 93
