Index of Symptom-to-FRU Error Messages
To use the information in this section to diagnose a problem:
1.
Find the error symptom in the left column.
2.
If directed to a check procedure, replace the FRU indicated in the check procedure.
If no check procedure is indicated, the first Action/FRU item listed in the right column is the most likely
cause.
NOTE:
If you cannot find a symptom or an error in this list and the problem remains, see “Undetermined
Problems” on page 80.
NOTE:
Normally, the processor fan should be operative, and the processor clock setting should be exactly set
to match its speed requirement before diagnosing any processor problems.
NOTE:
Ensure the memory modules are installed properly and the contact leads are clean before diagnosing
any system problems.
