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). You should use blue thermal grease (part number 01KP765) when replacing the
microprocessor if that grease is available in your country. If it is not available, use gray thermal grease (part
number 41Y9292).
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.
