Heat-Sink Mounting Brackets - Intergraph InterServe 90 System Reference Manual

To replace a processor module:
1. Remove the heat-sink lock from within the heat-sink fins, if necessary, by pressing the ends of
the lock inward and pulling lock outward.
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. Install the heat-sink lock between the heat-sink fins, if necessary, by sliding the lock between
the fins and pressing it onto the heat-sink lock mounting posts.

Heat-Sink Mounting Brackets

Pentium II and Pentium III 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.
4. 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.
