Replacing a microprocessor and heat sink

To install the microprocessor and heat sink on 4U server models with non-hot-swap power supplies, complete the following steps. For the 5U server model with hot-swap power supplies (Model name: 2582-F4x), please see the next sub-section.

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:

   • The microprocessor has two notches that are keyed to two tabs on the sides of the socket.
   • A triangle-shaped indicator on one corner of the microprocessor points to a 45-degree angle on the system board.
   • Do not use excessive force when you press the microprocessor into the socket.
5. Close the microprocessor bracket frame; then, close the microprocessor retention latch and lock it securely in place.
   
   
6. Install the heat sink:
   Attention

   Do not touch the thermal material on the bottom of the heat sink. Touching the thermal material will contaminate it. If the thermal material on the microprocessor or heat sink becomes contaminated, contact your service technician.
   1. Align the screw holes on the heat sink with the holes on the system board.
   2. Tighten the screws with a screwdriver, alternating among the screws until they are tight. If possible, each screw should be rotated two full rotations at a time. Repeat until the screws are tight. Do not overtighten the screws by using excessive force.
      
      
7. Reconnect any cables that you disconnected during the removal of the old microprocessor.
8. Secure the SATA signal cables with the retention-clips.
9. Install the air duct.
10. Install the side cover (see Replacing the side cover).
11. Stand the server back up in its vertical position.
12. Install the bezel (see Replacing the bezel).
13. Reconnect the external cables and power cords; then, turn on the attached devices and turn on the server.

8. Rotate the rear adapter-retention bracket to the closed (locked) position.
9. Stand the server back up in its vertical position.
10. Install and lock the side cover (see Replacing the side cover).
11. Reconnect the external cables and power cords; then, turn on the attached devices and turn on the server.
