Removing a PPM
The server PPMs provide the proper power to each processor. Each PPM must be installed in the correct
slot for the processor.
IMPORTANT: Processor socket 1 and PPM slot 1 must be populated at all times or the server does not
function properly.
IMPORTANT: Always install a PPM when you install a processor. The system fails to boot if the PPM is
missing.
To remove a PPM:
1. Power down the server (on page 16).
2. Remove the processor module ("Removing the processor module" on page 20).
