Processor replacement
Use the following procedures to remove and install a processor.
Attention:
Before you begin replacing a processor, make sure that you have an alcohol cleaning pad (part
number 00MP352) and gray thermal grease (part number 41Y9292).
Important:
The processor in your server can throttle in response to thermal conditions, temporarily lowering
its speed to reduce heat output. In instances where a few processor cores are throttled for an extremely
short time period (100 ms or less), the only indication might be an entry in the operating system event log
with no corresponding entry in the system XCC event log. If this situation occurs, the event can be ignored
and processor replacement is not required.
Remove the processor
Use this information to remove the processor. This procedure must be executed by a trained technician.
