Troubleshooting 169
Server fails to recognize new memory
Action:
1. Be sure the memory is the correct type for the server and is installed
according to the server requirements. Refer to the server documentation or
HP website (
http://www.hp.com ).
2. Be sure you have not exceeded the memory limits of the server or operating
system. Refer to the server documentation.
3. Be sure no Event List error messages (on page 278 ) are displayed in the
IML.
4. Be sure the memory is properly seated.
5. Be sure no conflicts are occurring with existing memory. Run the server
setup utility.
6. Test the memory by installing the memory into a known working server. Be
sure the memory meets the requirements of the new server on which you are
testing the memory.
7. Replace the memory. Refer to the server documentation.
PPM problems
Action: If the PPMs are not integrated on the system board:
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. If applicable, check the PPM LEDs to identify if a PPM failure occurred. For
information on LEDs, refer to the server documentation.
2. Reseat each PPM, and then restart the server.
3. If reseating the PPMs is not effective, remove all but one PPM, restart the
server to see if the PPM is working, and then install each PPM individually,
cycling power each time. Follow the warnings and cautionary information in
the server documentation.
