Microprocessor Microprocessor release lever bracket frame Microprocessor dust cover a. Press down and out on the release lever on the microprocessor socket taking it out of the closed and locked position. Lift up the release lever until it stops in the fully open position (approximately 135° angle) and the top edge of the release lever has moved away from the microprocessor socket. b. Lift the hinged microprocessor bracket frame into an open position. Remove the microprocessor dust cover from the bracket frame. Store the dust cover in a safe place. 5. Touch the static-protective package that contains the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package. Attention: Dropping the microprocessor during installation or removal can damage the contacts. Also, contaminants on the microprocessor contacts, such as oil from your skin, can cause connection failures between the contacts and the socket. 6. Position the microprocessor over the microprocessor socket. Use the triangular alignment cutout on the microprocessor socket and the triangular alignment mark on the microprocessor to assist you in aligning the microprocessor to the socket. Then, carefully place the microprocessor into the socket. Do not force the microprocessor, it only fits one way onto the socket.

Place the microprocessor bracket frame down over the microprocessor and the microprocessor socket to secure the microprocessor position on the socket. 8. Rotate the microprocessor release lever into a closed position. 9. Place the heat sink on top of the microprocessor with the thermal grease side down. Install the screws to secure the heat sink to the system board. Attention: Do not touch the thermal grease on the bottom of the heat sink after you remove the plastic cover. Touching the thermal grease will contaminate it. 24 IBM System x3550 Type 7978: Installation Guide
