1. Read "Safety information" on page 119 and "Installation guidelines" on page 37. 2. Turn off the server and all attached peripheral devices. Disconnect all power cords; then, disconnect all external signal cables from the server. 3. Remove the server cover (see "Removing the cover and bezel" on page 44); then, determine the socket where the microprocessor is to be installed. Attention: v Avoid touching the components and gold-edge connectors on the microprocessor. Ensure that the microprocessor is completely and correctly seated in the socket. Incomplete insertion might cause damage to the system board or to the microprocessor. v When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For information about handling these devices, see "Handling electrostatic discharge-sensitive devices" on page 122. Note: A new microprocessor comes in a kit with a VRM and a heat sink. 4. If you are installing a microprocessor in the microprocessor 2 socket, first install a VRM in the microprocessor 2 VRM slot (J42) and remove the protective cover from the microprocessor 2 socket. 5. Rotate the locking lever on the microprocessor socket from its closed and locked position until it stops or clicks in the fully open position (approximately 135° angle), as shown. Then, see the documentation provided with the microprocessor option for complete installation instructions. Attention: You must ensure that the locking 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.
