Install the processor board

Follow the instructions in this section to install the processor board.

About this task

A processor board provides different connectors or slots to connect different components or peripherals of the system for communication. The board and the supporting metal sheet constitute a base for the system board assembly. If the processor board fails, it must be replaced.

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.

Procedure

  1. Install the system I/O board, see Install the system I/O board.
