Dell PowerEdge 650 - Manual (Page 52)

It is possible to upgrade your processor to take advantage of future options in speed and functionality. Each processor and its associated level 2 (L2) cache
memory are contained in a pin grid array (PGA) package that is installed in a ZIF socket on the system board.
The following items are included in the processor upgrade kit:
l Processor
l Heat sink
Replacing the Processor
1. Open the system. See " Opening the System " in Troubleshooting Your System."
2. Remove both pieces of the cooling shroud.
3. Pushing down with one hand on the securing clip's rubber-coated tab, use the other hand to pull the latch on the securing clip on the left to release the
securing clip from the heat-sink posts. See Figure 6 -7 .
4. Remove the securing clip.
5. Repeat step 3 and step 4 to remove the securing clip on the right.
Figure 6-7. Removing the Securing Clip
6. Remove the heat sink.
If the heat sink uses a foil thermal interface material, set the heat sink upside down so as not to contaminate the interface material.
7. Pull the socket-release lever straight up until the processor is released from the socket. See Figure 6 -8 .
8. Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.
CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting
against electrostatic discharge.
NOTICE: The processor and heat sink can become extremely hot. Be sure the processor has had sufficient time to cool before handling.
NOTICE: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper
thermal conditions.
NOTICE: Be careful not to bend any of the pins when removing the processor. Bending the pins can permanently damage the processor.
