Follow these steps to remove a processor:
1. Remove the chassis cover as described in "Removing the Chassis Cover" on
page 21.
2. Disconnect the fan/heatsink cables from the system board.
3. Follow these steps to remove the fan/heatsink assembly from the processor:
– Disconnect the fan/heatsink cable from the system board. See Figure 2-50 for
the location of the cable connection.
– Push on the releasing tab to unhook the metal bracket that is facing the rear of
the system. See steps A and B in Figure 2-48.
– Lift the fan/heatsink assembly and unhook the other metal bracket. See step C
in Figure 2-48.
– Remove the fan/heatsink assembly from the processor.
Note: Avoid touching the thermal conductive grease on the bottom of the
fan/heatsink and the top of the processor.
4. Pull up the socket lever (see step D in Figure 2-48). The processor pins will be
automatically released from the socket holes.
5. Lift the processor from the socket as shown in Figure 2-48.
Caution: Do not touch the pins on the processor, so as to ensure long-term reliable
contact.
6. If you will now be using the system as a single-CPU system, this processor must be
replaced with a terminator board. See "Installing a Processor Terminator Board" on
page 86.
7. Install the chassis cover as described in "Installing the Chassis Cover" on page 23.
