Install A Processor And Heat Sink - Lenovo ThinkSystem SR650 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.
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

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 133 for a list of microprocessor-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.
• The PHM for your system might be different than the PHM shown in the illustrations.
• If you want to install the following processors to the server, ensure that the server chassis is twenty-four
2.5-inch-bay chassis and only one backplane is installed in the middle cage (for drive bays 8–15).
