CAUTION: To allow heat sink to draw as much heat as possible from the processor base, there must be good contact between the heat sink base and the top of the processor. To ensure good contact, you must apply thermal interface material. To apply the thermal grease compound: 1. Use a clean cloth dipped in rubbing alcohol to clean the contact surface on the heat sink and on the new processor. Wipe the contact surfaces several times to make sure that no particles or dust contaminants are evident. 2. Apply the thermal grease compound to the CPU contact surface. CAUTION: HP recommends using Shin-Etsu X-23-7783D thermal grease compound for your ProLiant server. 3. Apply all the grease to the top of the processor in one of the following patterns to insure even distribution. Figure 10 Processor top CAUTION: Never touch the bottom of the processor; any contaminant could prevent the mounting pads from making contact with the socket. CAUTION: Applying too much grease creates a gap between the contact surfaces, significantly reducing the ability of the heat sink to draw out heat. Installing the heat sink with excessive grease can also cause the grease to spread over the processor pins or the system board base, which can cause electrical shorts that damage the system. To install the new processor: 1. Insert the processor into the socket, using the key on the processor. 2. Engage the retention plate. 3. Engage the load lever. CAUTION: With the load lever and the retention plate disengaged, hold the processor by its edges and align it over the empty processor socket. Make sure that you properly align the processor with the orientation notch on the socket. Removal and Replacement Procedures 36

CAUTION:
Never touch the bottom of the processor; any contaminant could prevent the mounting
pads from making contact with the socket.
CAUTION:
Applying too much grease creates a gap between the contact surfaces, significantly
reducing the ability of the heat sink to draw out heat. Installing the heat sink with excessive grease
can also cause the grease to spread over the processor pins or the system board base, which can
cause electrical shorts that damage the system.
To install the new processor:
1.
Insert the processor into the socket, using the key on the processor.
2.
Engage the retention plate.
3.
Engage the load lever.
CAUTION:
With the load lever and the retention plate disengaged, hold the processor by its edges
and align it over the empty processor socket. Make sure that you properly align the processor with
the orientation notch on the socket.
