Dell PowerEdge M520 Systems Owner's Manual

Removing A Processor

  • CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
  1. Remove the blade from the enclosure.
  2. Open the blade.
    • WARNING: The processor and heat sink can become extremely hot. Be sure the processor has had sufficient time to cool before handling.
  3. If required, remove the cooling shroud.
    • CAUTION: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper thermal conditions.
  4. Loosen the retention sockets that secure the heat sink to the blade system board.
  5. Remove the heat sink.

  6. Use a clean, lint-free cloth to remove any thermal grease from the surface of the processor shield.
    • CAUTION: The processor is held in its socket under strong pressure. Be aware that the release lever can spring up suddenly if not firmly grasped.
  7. Position your thumb firmly over the processor socket-release lever and release the lever from the locked position. Rotate the lever 90 degrees upward until the processor is released from the socket.
  8. Hold the tab on the processor shield and rotate it upward and out of the way.
  9. If applicable, remove the socket protective cap from the processor shield. To remove the socket protective cap, push the cap from the inside of the processor shield and move it away from the socket pins.
    • NOTE: It is recommended that you install/remove the socket protective cap from the processor shield with the processor shield in the open position.
    • CAUTION: The socket pins are fragile and can be permanently damaged. Be careful not to bend the pins in the socket when removing the processor out of the socket.
  10. Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.
    • CAUTION: If you are permanently removing a processor, you must install a socket protective cap and a processor/DIMM blank in the vacant socket to ensure proper system cooling. The processor/DIMM blank covers the vacant sockets for the DIMMs and the processor.
