Removing a CPU

Removing a CPU

  • Only personnel authorized by Huawei and Huawei technical support personnel can remove a CPU from Huawei servers.
  • Do not wear ESD gloves because they may damage the pins on the CPU socket.


  1. Power off the server. For details, see Powering On and Off the RH5885 V3. Remove all power cables.
  2. Remove the chassis cover of the RH5885 V3. For details, see Removing the Chassis Cover.
  3. Remove the air duct of the RH5885 V3. For details, see Removing the Air Duct.
  4. Removed the CPU baffle and battery tray by lifting them.
  5. Wear an ESD wrist strap or ESD gloves. For details, see Safety Instructions.
  6. Remove the four screws that secure the heat sink. You are advised to loosen every two screws in the diagonal direction. See step (1) in Figure 5-61.

  7. Lift the heat sink slowly out of the RH5885 V3. See step (2) in Figure 5-61.

    There is a layer of thermal compound between the heat sink and the CPU. When the temperature is low, the thermal compound makes the heat sink and CPU securely adhere to each other. Before you remove the heat sink, use an air heater to heat and melt the thermal compound. Then, you can remove the heat sink easily.

  8. Do not use any tool or sharp object to lift the securing rod on the CPU socket. Otherwise, the CPU socket or CPU may be damaged.

    Raise the securing rod near the or label. See step (1) in Figure 5-62.

  9. Raise the securing rod near the or label. See step (2) in Figure 5-62.
  10. Open the CPU load plate, squeeze two sides (shown in Figure 5-63) of the CPU installation tool, and raise the tool with the CPU inside vertically. See steps (3) and (4) in Figure 5-62.
  11. Use a tissue to clean off any residual thermal paste from the CPU, and place the CPU installation tool with the CPU inside in an ESD bag.

    Ensure that CPU sockets are installed with CPUs or CPU socket covers during transportation and storage.
