2. Press the locking tabs on the top corners of the processor module inward, towards each
other, until they click into the release position.
3. Slide the processor module out of the retention module.
4. Remove the new processor from its antistatic package, and align the processor module
over the retention module. The processor module is keyed and fits only one way.
5. Press the processor module down until it seats.
6. Press the processor module locking tabs outward until they click into the locked position.
7. Connect the processor's cooling fan power cable to the processor fan power connector on
the system board.

Heat-Sink Mounting Brackets

Pentium II processors equipped with heat-sink fins use heat-sink locks fastened to mounting
brackets to secure them to the system board, providing additional stability to the processor
module. See the System Board Manual for connector and socket locations.
To replace a heat-sink mounting bracket:
1. Remove the processor module. See the "Processor Modules" for details.
2. Two mounting locks on the rear side of the system board secure the mounting bracket.
Remove these locks, and then remove the mounting bracket from the system board.
3. The heat-sink mounting bracket has two pins on the bottom and four pins on the top. The
bottom two pins are of different sizes. The size of the pins and the holes in the system
board determine the correct orientation.
Insert the new heat-sink mounting bracket into the appropriate holes on the system board.
The bracket will click when it is correctly inserted. Ensure the four top pins are closest to
the processor slot.
5. Lock the heat-sink mounting bracket to the system board by inserting the two mounting
locks into the pins of the heat-sink mounting bracket, which are below the system board.
The locks will click when they are securely fastened.

Retention Modules

Pentium II processors are secured to the system board using retention modules. See the
System Board Manual for connector and socket locations.
NOTE You do not need to replace a retention module to replace a processor module.
