Install A Processor And Heat Sink - Lenovo ThinkSystem SR550 Maintenance Manual

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), a processor, and a heat sink. All of these tasks require a Torx T30 driver.
"Read the
installation
Guidelines" on
page 53
Attention:
• Intel Xeon SP Gen 2 processors are supported on the system board with part number 01PE842. If you use
the system board with part number 01GV277, update your system firmware to the latest level before
installing an Intel Xeon SP Gen 2 processor. Otherwise, the system cannot be powered on.
• 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.
• Remove and install only one PHM at a time. If the system board supports multiple processors, install the
PHMs starting with the first processor socket.
• 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.
• 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.
Notes:
• PHMs are keyed for the socket where they can be installed and for their orientation in the socket.
• See

server. All processors on the system board 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 "Firmware updates" on page 9.
• Installing an additional PHM can change the memory requirements for your system. See "Memory module
installation rules" on page 126 for a list of microprocessor-to-memory relationships.
• If you are going to install Intel Xeon 6230N, 6230T, or 5220T processor, use the heat sink with part number
01KP652 or 01KP653.
• Optional devices available for your system might have specific processor requirements. See the
documentation that comes with the optional device for information.
Before installing a PHM:
Note: The heat sink, processor, and processor retainer for your system might be different than those shown
in the illustrations.
1. Remove the existing PHM, if one is installed. See "Remove a processor and heat sink" on page 144.
2. If you are replacing a heat sink, replace the processor retainer. Processor retainers should not be reused.
