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). The procedure must be executed by a trained technician.

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 the part without proper training and qualification.
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. Make preparations for this task.
    1. Remove the 2U compute shuttle. See Remove the 2U compute shuttle.
