About this task

Important
  • (Lenovo trained technicians only) After replacing the Firmware and RoT Security Module, update the UEFI, XCC and LXPM firmware to the specific version supported by the server. For detailed information on how to update the firmware, see Tip for replacing a Firmware and RoT Security Module (Lenovo trained technicians only).
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.
