Remove the system I/O board

Follow the instructions to remove the system I/O board.

About this task

  • 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 Firmware and RoT Security module, see Remove the Firmware and RoT Security Module.
  3. Remove the MicroSD card, see Remove the MicroSD card.
  4. Separate the system I/O board from the processor board.
    To prevent the contact of the IO board from damage, pinch and lift the plunger on the IO board upward a little and pull out the IO board outward. During the entire pulling action, ensure that the IO board remains as horizontal as possible.

    1. Remove the screws that secure the system I/O board.
    2. Lift and hold the plunger and slide the system I/O board towards the rear to disengage it from the processor board.

After you finish

  • Before you return the processor board, make sure that you install the processor socket covers to the new processor board.

  • If replacing a new system I/O board, transfer the MicroSD card from the old system I/O board to the new one. See Remove the MicroSD card and Install the MicroSD card.

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