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 long-shank, Torx T30
screwdriver with a minimum shank length of 105 mm (4.1 inches).

Attention:
• 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.
Notes:
• PHMs are keyed for the socket where they can be installed and for their orientation in the socket.
• See
http://www.lenovo.com/us/en/serverproven/
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 PHM or replacement processor, update your system firmware to the latest level.
See “Firmware updates” on page 7.
• Installing an additional PHM can change the memory requirements for your system. See “DIMM
installation rules” on page 110 for a list of processor-to-memory relationships.
• 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 160.
2. Replace the processor retainer of the replacement processor.
Note: Replacement processors come with both rectangular and square processor retainers. A
rectangular retainer comes attached to the processor. You must remove the rectangular retainer and
replace it with a square retainer. The rectangular retainer can be discarded.
