Processor and heat sink replacement (trained technicians only)
Follow the instruction in this section to replace an assembled processor and heat sink, known as a processor-heat-sink module (PHM), a processor, or a heat sink.
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.
When the server has a Compute Complex Neptune Core Module installed, you must apply for a shipping bracket FRU first if you need to install or remove the system board assembly or processor. However, when replacing the old Compute Complex Neptune Core Module with a new one, you do not need to apply for a shipping bracket FRU as the new module package contains it.
