Install the system I/O board and interposer board

Follow instructions in this section to install the system I/O board and interposer board.

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.

  • Power off the server and peripheral devices, disconnect the power cords from the primary chassis, then disconnect the power cords from the secondary chassis. 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. Install the system I/O board to the bracket.

    1. Align the holes in the interposer board with the pins on the bracket; then, lower the interposer board onto the bracket and use both hands to push the interposer board by its edges into the contacts on the system I/O board.
      Note
      To prevent the contacts of the system I/O board from damage, ensure that the interposer board is aligned correctly with the contacts on the system I/O board, and remains as horizontal as possible during the insertion.
