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 the memory is properly seated.
4. Be sure no conflicts are occurring with existing memory. Run the server setup utility.
5. 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.
6. 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 with the access panel open or removed. Operating
the server in this manner 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.
