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.

Important

  • This task must be operated by trained technicians that are certified by Lenovo Service. Do not attempt to remove or install it without proper training and qualification.

  • When removing the memory modules, label the slot number on each memory module, remove all the memory modules from the system board assembly, and set them aside on a static-protective surface for reinstallation.

  • When disconnecting cables, make a list of each cable and record the connectors the cable is connected to, and use the record as a cabling checklist after installing the new system board assembly.

Attention

  • 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.

  • Keep static-sensitive parts in their static-protective packages until installation to prevent exposure to static electricity. Handle the parts with an electrostatic-discharge wrist strap or other grounding systems. Place the parts on a static-protective surface.

Procedure

  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.
      Attention
      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.

After you finish

Important

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.
