Removal and replacement procedures 45
Processor installation
WARNING: To reduce the risk of personal injury from hot surfaces, allow the heat sink and the
processor to cool before touching them.
CAUTION: To prevent the heat sink from tilting to one side during installation/removal procedures,
observe a diagonally opposite pattern (an “X” pattern) when loosening and tightening the four
spring loaded screws.
The procedure for replacing the current processor consists of five major steps which are as follows:
1. Remove the heat sink.
2. Remove the current processor.
3. Apply the thermal compound.
4. Install the new processor.
5. Install the CPU heatsink.
To remove the heat sink:
1. Prior to removing the heat sink, power on the system for a few minutes to soften the thermal
compound, so that the fan can easily be removed.
2. Perform the pre-installation procedure.
3. Lay the server on its side (components showing).
4. Remove the heat sink.
a. Disconnect the heat sink cable from its system board connector (1).
b. Use a T-15 Torx screwdriver to loosen the four spring-loaded screws of the heat sink (2).
c. Lift the heat sink away from the system board (3).
You may need to rotate the heat sink a few degrees clockwise and counterclockwise to break
the thermal compound bond.
