due to a processor problem.

Processor Power Modules

If the server configuration includes one or more PPMs and one fails, the server is
forced into a reset condition and does not power up. To check for failure if the PPMs
are not integrated on the system board:
CAUTION: Never operate the server for an extended period of time if an access
panel is removed. Doing so can cause thermal damage to drives and components
and can void your system warranty.
1. Briefly remove the appropriate access panel to inspect.
2. Try reseating each PPM.
3. If reseating the PPMs is not effective, replace each PPM one at a time and test.

Possible Cause
Processors are incorrectly
installed in your server.
Processors are unsupported
by your server.
Bus core ratio may be set
incorrectly.
Possible Solution
Be sure that each processor is
correctly installed in your
server, as detailed in your
server-specific user
documentation.
Be sure that each processor is
supported by your server.
Refer to your server-specific
user documentation for
processor requirements.
Be sure that the appropriate
jumpers and switches are set
correctly for your server,
especially if you have recently
added new processors. Refer
to your server-specific user
documentation for jumper and
switch settings.
