Installing a microprocessor and fan sink To install the microprocessor, complete the following steps: 1. Touch the static-protective package that contains the microprocessor to any unpainted metal surface on the server. Then, remove the microprocessor from the package. 2. Remove the protective cover, tape, or label from the surface of the microprocessor socket, if any is present. 3. Rotate the release lever on the microprocessor socket to the fully open position. Attention: Make sure that the release lever on the microprocessor socket is in the fully open position before you insert the microprocessor in the socket. Failure to do so might result in permanent damage to the microprocessor, microprocessor socket, and system board. 4. Carefully grasp the microprocessor and place the microprocessor into the microprocessor socket. Note: To maintain correct orientation between the microprocessor and the microprocessor socket during installation, observe the following information: v The microprocessor has two notches that are keyed to two tabs on the sides of the socket. v A triangle-shaped indicator on one corner of the microprocessor points to a 45-degree angle on one corner of the socket. v Do not use excessive force when you press the microprocessor into the socket.
