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
Attention:
• Read
“Installation Guidelines” on page 55 and “Safety inspection checklist” on page 56 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” on page 73.
• 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.
• Each processor socket must always contain a cover or a PHM. When removing 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 system supports multiple processors, install the PHMs
starting with the first processor socket.
Notes:
• The heat sink, processor, and processor carrier for your 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.
• See
https://serverproven.lenovo.com for a list of processors supported for your server. All processors must
have the same speed, number of cores, and frequency.
• Before you install a new PHM or replacement processor, update your system firmware to the latest level.
See
“Update the firmware” on page 445.
The following illustration shows the components of the PHM.
