Dell Precision Rack 7910 Owner's Manual

Installing a processor

1. Unpack the new processor.
   If the processor has previously been used in a system, remove any remaining thermal grease from the processor using a lint-free cloth.
2. Locate the processor socket.
3. If applicable, remove the socket protective cap.
4. Release the open first socket-release lever near the unlock icon by pushing the lever down and out from under the tab.
5. Similarly, release the close first socket-release lever near the lock icon by pushing the lever down and out from under the tab. Lift the lever 90 degrees upward.
6. Hold the tab near the lock symbol on the processor shield and lift it up and out of the way.
7. To install the processor in the socket:
   CAUTION:Positioning the processor incorrectly can permanently damage the system board or the processor. Be careful not to bend the pins in the socket.

   CAUTION:While removing or reinstalling the processor, wipe your hands of any contaminants. Contaminants on the processor pins such as thermal grease or oil can damage the processor.
   1. Align the processor with the socket keys.
      CAUTION:Do not use force to seat the processor. When the processor is positioned correctly, it engages easily into the socket.
   2. Align the pin-1 indicator of the processor with the triangle on the .
   3. Place the processor on the socket such that the slots on the processor align with the socket keys.
      CAUTION:Do not use force to seat the processor. When the processor is positioned correctly, it engages easily into the socket.
   4. Close the processor shield.
   5. Lower the close first socket-release lever near the lock icon and push it under the tab to lock it..
   6. Similarly, lower the open first socket-release lever near the unlock icon and push it under the tab to lock it.
8. To install the heat sink:
   1. If applicable, remove the existing thermal grease from the heat sink using a clean lint-free cloth.
   2. Apply thermal grease on the top of the processor. Use the thermal-grease syringe included with your processor kit.
      CAUTION:Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.

      

      1. processor
      2. thermal grease
      3. thermal-grease syringe

      NOTE:The thermal-grease is intended for one-time use only. Dispose of the syringe after you use it.
   3. Place the heat sink onto the processor.
   4. Tighten the four screws to secure the heat sink to the system board.
      NOTE:Tighten the screws diagonally opposite to each other. Do not over-tighten the heat sink retention screws when installing the heat sink. To prevent over-tightening, tighten the retention screw until resistance is felt, and stop once the screw is seated. The screw tension should be no more than 6 in-lb (6.9 kg-cm).
