Install a processor-heat-sink module
This task has instructions for installing processors and heat sinks. Heat sink replacement requires a Torx
#T20 screwdriver.
About this task
CAUTION:
Make sure that all server power cords are disconnected from their power sources before performing
this procedure.
Attention:
• Read “Installation Guidelines” on page 134 to ensure that you work safely.
• Power off the server and disconnect all power cords for this task.
• 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.
• The heat sink is necessary to maintain proper thermal conditions for the processor. Do not power on the
server with the heat sink removed.
• 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 electrical connectors in the processor socket. Do not remove the grease cover from
a heat sink until you are instructed to do so.
• See
https://static.lenovo.com/us/en/serverproven/index.shtml for a list of processors supported for your
server. All processors on the system board must have the same speed, number of cores, and frequency.
• Before you install a new processor, update your system firmware to the latest level. See “Update the
firmware” on page 238.
• Optional devices available for your system might have specific processor requirements. See “Technical
rules for processor and heat sink” on page 139.
