Install the system I/O board

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

About this task

Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.
  • Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.
  • 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. Hold the system I/O board at an angle, and insert it into the FIO/PCI cage.
  2. Lower the system I/O board; then, align the notches on the system I/O board with the retainers as illustrated.
  3. Connect the cable to the system I/O board.
  4. Tighten the four screws to secure the system I/O board and the cable.

  6. Update the XCC/LXPM/FPGA SCM/LXUM firmware. See Update the firmware.
  7. Perform OneCLI commands or XCC actions to restore the UEFI and XCC settings. See OneCLI commands that restore configuration settings or Using XCC to restore the BMC configuration.
  8. Reinstall the FoD key.
  9. If hiding TPM or updating TPM firmware is needed, see Hide/observe TPM or Update the TPM firmware.
  10. Optionally, enable UEFI Secure Boot. See Enable UEFI Secure Boot.
  • Hide/observe TPM
    TPM is enabled by default to encrypt data transfer for system operation. Optionally, you can disable TPM using Unified Extensible Firmware Interface (UEFI) or Lenovo XClarity Essentials OneCLI.
  • Update the TPM firmware
    Optionally, you can update the TPM firmware using Lenovo XClarity Essentials OneCLI.
