This index supports the JS20 Type 8842 blade 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 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.
