Processor And Heat Sink Replacement; Remove A Processor And Heat Sink - Lenovo thinksystem SR630 Maintenance Manual

Processor and heat sink replacement

Use the following procedures to replace an assembled processor and heat sink, known as a processor-heat-
sink module (PHM), a processor, or a heat sink.
Attention: Before you begin replacing a processor, make sure that you have an alcohol cleaning pad (part
number 00MP352) and blue thermal grease (part number 01KP765). Do not use gray thermal grease (part
number 41Y9292) when replacing a ThinkSystem SR630 processor.
Important: The processor in your server can throttle, temporarily lowering speed to reduce heat output, in
response to thermal conditions. In instances where the throttling period is of extremely short duration (100
ms or less), the only indication will be an entry in the event log. In these instances the event can be ignored
and processor replacement is not required.

Remove a processor and heat sink

This task has instructions for removing 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.
Before you remove 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 top cover. See "Remove the top cover" on page 42.
2. Remove the air baffle. See "Remove the air baffle" on page 45.
3. Remove any parts and disconnect any cables that might impede your access to the PHM.
Complete the following steps to remove a PHM.
Watch the procedure. A video of the removal process is available:
