Removing and replacing the heatsink processor assembly

This procedure shows a standard heatsink as an example. The removal process is the same for all heatsinks.

Hewlett Packard Enterprise recommends identifying the processor, heatsink, and socket components before performing this procedure.

Prerequisites
Before you perform this procedure, make sure that you have the T-30 Torx screwdriver available.
Procedure
  1. Observe the following cautions:
    CAUTION: When handling the heatsink, always hold it along the top and bottom of the fins. Holding it from the sides can damage the fins.
    CAUTION: THE CONTACTS ARE VERY FRAGILE AND EASILY DAMAGED. To avoid damage to the socket or processor, do not touch the contacts.
  2. Power down the server blade.
  3. Remove the server blade from the chassis.
  4. Remove the top cover.
  5. Remove the air baffle.
  6. Observe the following cautions.
    CAUTION: Be sure to loosen each heatsink nut in the order indicated. Otherwise, damage might occur to the heatsink or processor.
    CAUTION: Install the processor heatsink assembly as soon as possible after removing it. Do not leave the processor socket unpopulated for extended periods of time.
  7. Remove the processor heatsink assembly:
    1. Allow the heatsink to cool.
    2. Using a T-30 Torx screwdriver, loosen the heatsink nuts.

    3. Lift the processor heatsink assembly up and away from the system board.

To replace the heatsink processor assembly:

  1. Install the processor heatsink assembly:
    1. Locate and align the Pin 1 indicator on the processor frame and the socket.
    2. Align the processor heatsink assembly with the heatsink alignment posts and gently lower it down until it sits evenly on the socket.
      The heatsink alignment posts are keyed. The processor will only install one way.

      A standard heatsink is shown, your heatsink might look different.

      CAUTION: Be sure to tighten each heatsink nut fully in the order indicated. Otherwise, boot failure or intermittent shutdowns might occur.
    3. Using a T-30 Torx screwdriver, tighten the nuts until they stop.
  2. Install the air baffle.
  3. Install the top cover.
  4. Install the server blade in the chassis.
  5. Power up the server blade.
