Lever closed Lever fully open Note: Two of the microprocessor sockets are mounted on the microprocessor board with the microprocessor-release lever on the opposite side. These sockets are rotated 180° on the microprocessor board. Be sure to verify the orientation of the socket before installing the microprocessor. 8. Touch the static-protective package that contains the new microprocessor to any unpainted metal surface on the outside of the server; then, remove the microprocessor from the package. Attention: To avoid bending the pins on the microprocessor, do not use excessive force when pressing it into the socket 9. Position the microprocessor over the microprocessor socket and carefully press the microprocessor into the socket.

Open the heat-sink retaining clip: a. Press down on the center of the heat-sink retaining clip. This will cause the clip to flex and release it from the tabs on the heat-sink socket. b. Lift the heat-sink retaining clip to the fully open position (approximately 135° angle). 12. Remove the heat sink from its package and remove the cover from the bottom of the heat sink. 13. Remove the release liner and orient the heat sink above the microprocessor; then, press the heat sink into place and close the heat-sink release lever. 14. If you have other microprocessors to install, do so now by repeating steps 5 through 13. 15. Install the air baffle in the microprocessor tray. 16.
