Install the system I/O board or processor board

Follow instructions in this section to install the system I/O board or processor board.

About this task

Important

This task must be operated by trained technicians that are certified by Lenovo Service. Do no attempt to remove or install it without proper training and qualification.

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.

  • 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 system.

Firmware and driver download: You might need to update the firmware or driver after replacing a component.

Procedure

  1. Touch the static-protective package that contains the new part to any unpainted surface on the outside of the server; then, take the new part out of the package and place it on a static-protective surface.
  2. Depending on your need, do one of the following:
    • If you are going to replace the system I/O board and reuse the processor board, install a new system I/O board onto the processor board.

    • If you are going to replace the processor board and reuse the system I/O board, install the existing system I/O board onto a new processor board.

    1. Align the system I/O board with the connector on the processor board, and use both hands to push the system I/O board and slightly insert it into the connector.
      Note
      To prevent the contacts of the system I/O board from damage, ensure that the system I/O board is aligned correctly with the connector on the processor board, and remains as horizontal as possible during the insertion.

    2. Lower the system I/O board onto the supporting sheet metal. Make sure the plunger engages with the supporting sheet metal.
    3. Install the screws to fix the system I/O board into place.
  3. If you installed a new system I/O board onto the processor board, install the firmware and RoT security module and MicroSD card that was removed from the old system I/O board onto the new system I/O board. See Install the firmware and RoT security module and Install the MicroSD card.
  4. Place the system board assembly in the chassis.

    1. Grasp the plunger and blue handle; then, insert the shorter side of the system board assembly into the chassis.
    2. Lower the longer side of the system board assembly down into the chassis.
    3. Slide the system board assembly towards the rear of the chassis until the plunger clicks into place. Ensure that rear connectors on the system I/O board are inserted into the corresponding holes in the rear panel.
