Ppm Problems - Compaq ML530R - HP ProLiant - 128 MB RAM Troubleshooting Manual

Test the memory by installing the memory into a known working server. Be sure the memory meets the
6.
requirements of the new server on which you are testing the memory.
Replace the memory. See the server documentation.
7.
Server fails to boot, all DIMM LEDs illuminate amber, ....
...the health LED is blinking red, the system emits continuous beeps, and an entry is logged to the Integrated
Management Log (IML)
Possible cause: The server is an HP ProLiant G6 server with 5500-series Xeon processors installed. The
DIMMs are not installed according to the server requirements.
Action: Be sure the memory is the correct type for the server and is installed according to the server
requirements.
•
Do not mix Unbuffered and Registered PC3 DIMMs.
•
Populate DIMM slots for a processor only if the processor is installed.
•
If Unbuffered DIMMs are installed, each channel supports a maximum of two DIMMs.
•
If quad-rank DIMMs are installed for a processor, a maximum of two DIMMs can be installed on each
channel for that processor.
•
If a channel contains quad-rank DIMMs, the quad-rank DIMM must be installed first on that channel.
For more information, see the server documentation on the HP website (http://www.hp.com/support).
If the system is configured with HP iLO 2 Firmware version 1.75, the IML message reports the following
message:
Uncorrectable Memory Error (Module Unknown)
This does NOT indicate a failed DIMM; this only indicates a DIMM configuration error.
If the system is configured with HP iLO 2 Firmware version 1.77 or later, the IML message reports the
following message:
Memory Configuration Error: System boot halted
For more information, see the server documentation on the HP website (http://www.hp.com/support).

PPM problems

Action: If the PPMs are not integrated on the system board:
CAUTION:
Operating the server in this manner results in improper airflow and improper cooling that can
lead to thermal damage.
If applicable, check the PPM LEDs to identify if a PPM failure occurred. For information on LEDs, refer to
1.
the server documentation.
Reseat each PPM, and then restart the server.
2.
If reseating the PPMs is not effective, remove all but one PPM, restart the server to see if the PPM is
3.
working, and then install each PPM individually, cycling power each time. Follow the warnings and
cautionary information in the server documentation.
Do not operate the server for long periods with the access panel open or removed.
