Install a heat sink Torx T30 nut

This task has instructions for installing a PEEK (Polyether ether ketone) Torx T30 nut on the heat sink.

About this task

  • 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.

  • 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.

  • Do not touch the processor contacts. Contaminants on the processor contacts, such as oil from your skin, can cause connection failures.

The heat sink, processor, and processor carrier for your system might be different from those shown in the illustrations.
Firmware and driver download: You might need to update the firmware or driver after replacing a component.
