To remove the component:

  1. Power down the server.
  2. Extend or remove the server from the rack (Extend the server from the rack, Remove the server from the rack).
  3. Remove the access panel.
  4. Remove the air baffle.
  5. If an optional redundant fan is located next to the processor, remove the fan.
  6. Open the processor retaining bracket.

  7. Remove the heatsink.

    To loosen the bond created by the thermal grease, use a rocking motion toward the front and rear of the server while lifting the heatsink.

  8. Open the processor locking lever.
  9. Remove the processor.

    Removing the processor

Before installing the reusable heatsink, clean the heatsink and prepare the processor:

  1. Use the alcohol prep pads provided to remove all thermal grease from the heatsink.
  2. After installing the processor, and before installing the heatsink, apply the provided thermal grease in an even layer to the top of the processor.

To replace the component, reverse the removal procedure.

CAUTION: Always wear an antistatic wrist strap when working inside the server.

CAUTION: Failure to completely open the processor locking lever prevents the processor from seating during installation, leading to hardware damage.

CAUTION: When installing a processor, be sure to secure the processor using the processor socket lever before closing the processor retaining bracket. Failure to do so will result in physical damage to the processor and server.

CAUTION: To prevent possible server malfunction, do not mix processors of different types.

CAUTION: To prevent possible server malfunction or damage to the equipment, be sure to align the processor pins with the corresponding holes in the socket.

IMPORTANT: If upgrading processor speed, update the system ROM before installing 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.

IMPORTANT: If you replace a failed processor or processors, clear the status log in RBSU after powering up the server. For RBSU procedures, refer to the Documentation CD.
