Installing and Configuring
Removing a Processor and Heatsink
Use this procedure to remove a processor and its heatsink. The heatsink with cooling fan
must be removed first, before removing the processor.
CAUTION: Always wear a wrist-strap and use a static-dissipating work surface connected to
the chassis when handling components. Be sure the metal of the wrist strap contacts your
skin.
Before you touch the processor to remove it, touch a grounded, unpainted metal surface on
the HP server to discharge static electricity.
1. Disconnect the cooling fan connector from its respective cooling fan connector on the
system board.
2. Open the locking levers on both brackets. Refer to Figure 2-18.
3. Lift the heatsink away from the processor and out of the server.
4. Open the ZIF lever to allow removal of the processor. Refer to Figure 2-15.
5. Grasp the processor by its edges, lift it out of the socket, and place it on a static-
dissipating work surface or into an anti-static bag.
