Troubleshooting 125
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.

Action:
CAUTION: Do not operate the server for long periods without
the access panel. Operating the server without the access panel results
in improper airflow and improper cooling that can lead to thermal
damage.
1. Check the server LEDs to see if any statuses indicate the source of the
problem. For LED information, refer to the server documentation.
2. Remove all power sources to the server.
3. Be sure no loose connections (on page 108
) exist in the area.
4. Be sure each component in the area is working. Refer to the section for each
component in this guide.
If you cannot determine the problem by checking the specific area, perform each
of the following actions. Restart the server after each action to see if the problem
has been corrected.
• Reseat all I/O expansion boards.
