Troubleshooting 57
Processor problems
Action :
1. If applicable, check the processor LEDs to identify if a PPM failure occurred.
For information on LEDs, refer to the server documentation.
2. Be sure each processor is supported by the server and is installed properly.
Refer to the server documentation for processor requirements.
3. Be sure the server ROM is up to date.
4. Be sure you are not mixing processor stepping, core speeds, or cache sizes if
this is not supported on the server. Refer to the server documentation for
more information.
CAUTION: Removal of some processors and heatsinks
require special considerations for replacement, while other processors
and heatsinks are integrated and cannot be reused once separated. For
specific instructions for the server you are troubleshooting, refer to
processor information in the Hardware options installation (on page
17 )
section on the Documentation CD.
5. If the server has only one processor installed, replace it with a known
functional processor. If the problem is resolved after you restart the server,
the original processor failed.
6. If the server has multiple processors installed, test each processor:
a. Remove all but one processor from the server. Replace each with a
processor terminator board or blank, if applicable to the server.
b. If the server includes PPMs that are not integrated on the system board,
remove all PPMs from the server except for the PPM associated with the
remaining processor.
c. Replace the remaining processor with a known functional processor. If
the problem is resolved after you restart the server, a fault exists with one
or more of the original processors. Install each processor and its
associated PPM (if applicable) one by one, restarting each time, to find
the faulty processor or processors. Be sure the processor configurations
at each step are compatible with the server requirements.
