Install the upper processor board (CPU BD)

Follow the instructions in this section to install the upper processor board (CPU BD).

About this task

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.

  • If the server is installed in a rack, remove the server from the rack. See Remove the server from rails.

Firmware and driver download: You might need to update the firmware or driver after replacing a component.
