Removing a Processor

Removing a Processor

  • Only Huawei technical support or personnel authorized by Huawei can remove the processors from Huawei servers.
  • Do not wear ESD gloves during processor replacement. The gloves may catch on pins on the processor socket and damage it.


  1. Power off the server node.

    For details, see Power-Off Procedure.

  2. Remove the server node.

    For details, see Removing an XH321 V5.

  3. Place the server node on the ESD workstation.
  4. Remove the air duct.

    For details, see Removing the Air Duct.

  5. Determine the position of the processor.

    Figure 8-32 Positions of processors

  6. Remove the conjoined heat sink and processor carrier.

    1. Use a Phillips screwdriver to loosen the four screws (marked 2 in the label) in the middle of the heat sink in a diagonal sequence. See (1) in Figure 8-33.
    2. Use a Phillips screwdriver to loosen the two diagonal screws (marked 1 in the label) on the heat sink. See (2) in Figure 8-33.
    3. Lift the heat sink and place it upside down on the ESD desk.
    4. Insert a flat-head screwdriver into the groove of the processor carrier, and twist it to pry up one side of the carrier. See (3) in Figure 8-33.

      Insert only the tip of the flat-head screwdriver. Do not apply excessive force.

    5. Holding the other end of the carrier, remove the carrier and processor in the arrow direction. See (4) and (5) in Figure 8-33.

  7. Remove the processor.

    • When removing a processor, hold the processor and its carrier to prevent the processor from falling off.
    • To prevent damage to the pins, do not touch the pins of the processor socket or the corresponding area on the processor.
    • Keep the processor away from the chassis to prevent thermal compound from falling off.
    1. Bend the edge of the carrier with the triangular hole to release the processor from the carrier.
      Figure 8-34 Removing a processor (1)
    2. Hold the two sides of the processor and lift it.
      Figure 8-35 Removing a processor (2)

  8. Place the removed component in an ESD bag.

    Clean the removed processor and put it into an ESD bag.

  9. Install a processor socket cover.

    • Perform this operation only when a processor is not installed immediately.
    • The processor socket cannot be exposed and must be covered by a processor or cover during transportation and storage.
    1. Aligning the processor socket cover with the guide pin on the processor socket, place the cover on the processor socket. See (1) in Figure 8-36.
    2. Press the positions shown by (2) in Figure 8-36 until you hear a click.
