Install the system I/O board

Follow the instructions in this section to install the system I/O board, also known as Datacenter Secure Control Module (DC-SCM).

About this task

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.

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.

  • To avoid component damage, connect the power cords last.

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. Install the MicroSD card removed from the old system I/O board onto the new system I/O board. See Install the MicroSD card.
  3. Install the new system I/O board onto the processor board.
    Figure 1. Installing the system I/O board onto the processor board

    1. Align the contacts on the system I/O board with the slots 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. Install the screws to fix the system I/O board into place.
  4. Install the system board assembly to the server.

    1. Hold the release pins 1 and 2 at the same time and lift the system board assembly up.
    2. Lower the system board assembly into the chassis as illustrated above.
    3. Slide the system board assembly to the rear of the server until the system board assembly snaps into position. Ensure that:

      • The rear connectors on the new system board assembly are inserted into the corresponding holes in the rear panel.

      • The release pin 2 secures the system board assembly in place.

After you finish

  1. Install any components that you have removed before the removal of system I/O board.

  2. Push the power supply units in place. Ensure that they are connected to the system board assembly.

  3. Reconnect all the required cables to the same connectors on the system board assembly. See Internal cable routing.

  4. Ensure that all components have been reassembled correctly and that no tools or loose screws are left inside the server.

  5. Reinstall the top cover. See Install the top cover.

  6. If the sever was installed in a rack, reinstall the server into the rack. See Server replacement.

  7. Reconnect external cables and power cords to the server.

    Attention
    To avoid component damage, connect the power cords last.

  8. Power on the server and any peripheral devices. See Power on the server.

  9. If hiding TPM or updating TPM firmware is needed, see Hide/observe TPM or Update the TPM firmware.

  10. Update the XCC/LXPM/FPGA SCM/UEFI/LXUM firmware. See Update the firmware

  11. Restore the server configuration. See Restore the server configuration.

  12. Re-install the FoD key.

  13. Optionally, enable Secure Boot. See Enable UEFI Secure Boot.
