Hardware options installation 37
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
corresponding PPM is missing.
To install a processor:
1. Power down the server (on page 22).
2. Extend the server from the rack (on page 22).
3. Remove the access panel (on page 23).
4. Open the heatsink retaining bracket.
CAUTION: The pins on the processor socket are very fragile. Any damage to them may
require replacing the system board.
CAUTION: Failure to completely open the processor locking lever prevents the processor from
seating during installation, leading to hardware damage.
