4. Loosen the three captive screws securing the microprocessor shield to the microprocessor module.
5. Remove the microprocessor shield.
6. Rotate the arm of the thermal cooling assembly up and away from the microprocessor module.
NOTICE: When removing the microprocessor module, pull the module straight up. Do not move the tool from side to side to
extract the processor board.
7. Use a microprocessor extractor tool to remove the microprocessor module.
The tool fits on the left side of the module aligned with white marks on the front and back edge of the processor
board (see Figure
Replacing the Microprocessor Module
NOTICE: Proper seating of the microprocessor module requires a considerable amount of force (approximately 35
pounds [16 kilograms]) applied above the module connector. A microprocessor module that is not properly seated
can result in an intermittent connection and subsequent failures.
1. Align the microprocessor connector on the left side of the board and press down firmly on the metal plate that is
directly over the connector.
When the microprocessor module is seated, all four corners must be at the same height. If one or more corners
of the module are higher than the others, the module is not seated correctly.
2. To ensure the microprocessor module is fully seated, apply pressure directly over the corner without the mounting
screw hole.
3. Rotate the arm of the thermal cooling assembly into place.
4. Replace the microprocessor shield.
5. Replace the two 3-mm screws that secure the thermal cooling assembly arm and shield to the microprocessor
module.
6. Tighten the three captive screws on the corners of the shield to secure the microprocessor module and shield.
