Install a processor and heat sink
This task has instructions for installing an assembled processor and heat sink, known as a processor-heat-sink module (PHM). This task requires a Torx T30 driver. This procedure must be executed by a trained technician.
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 systems.
Each processor socket must always contain a cover or a PHM. When removing or installing a PHM, protect empty processor sockets with a cover.
Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause connection failures.
Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage components, such as the electrical connectors in the processor socket.
Remove and install only one PHM at a time. If the processor board supports multiple processors, install the PHMs starting with the first processor socket.
To ensure the best performance, check the manufacturing date on the new heat sink and make sure it does not exceed 2 years. Otherwise, wipe off the existing thermal grease and apply the new grease onto it for optimal thermal performance.
The heat sink, processor, and processor carrier for the system might be different from those shown in the illustrations.
PHMs are keyed for the socket where they can be installed and for their orientation in the socket.
Before you install a new PHM or replacement processor, update your system firmware to the latest level.
