Remove the processor board

Follow instructions in this section to remove the processor board.

About this task

A processor board provides different connectors or slots to connect different components or peripherals of the system for communication. The board and the supporting metal sheet constitute a base for the system board assembly. If the processor board fails, it must be replaced.

  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding systems.


  1. Prepare your server.
    1. Remove the top cover. See Remove the top cover.
    2. If your server comes with an air baffle, remove it first. See Remove the air baffle.
    3. If your server comes with a rear drive assembly, remove it first. See Remove the 2.5-inch rear drive assembly.
    4. Record where the cables are connected to the system board assembly; then, disconnect all the cables.
      Disengage all latches, cable clips, release tabs, or locks on cable connectors beforehand. Failing to release them before removing the cables will damage the cable connectors on the system board assembly. Any damage to the cable connectors may require replacing the system board assembly.
    5. Remove any of the following components that are installed on the system board assembly and put them in a safe, static-protective place.
    6. Pull out the power supplies gently. Ensure that they are disconnected from the system board assembly.
  2. Remove the system board assembly from the chassis.

    1. Hold the lift handle 1 and lift the release pin 2 at the same time and slide the system board assembly toward the front of the server.
    2. Lift the system board assembly out of the chassis.
  3. Remove the Firmware and RoT Security module, see Remove the Firmware and RoT Security Module.
  4. Remove the system I/O board, see Remove the system I/O board.
Figure 2. The processor board

The processor board comes with a supporting metal sheet. No further removal is needed.

After you finish


Before you return the system board assembly, make sure that the processor socket is covered. There is a processor external cap covering the processor socket on the new system board assembly. Slide the processor external cap out from the processor socket on the new system board assembly, and install the external cap on the processor socket on the removed system board assembly.

If you are planning to recycle the system board assembly, follow the instructions in Hardware disassembling for recycle for compliance with local regulations.
