Lenovo ThinkSystem SR630 V4 - Processor and Heat Sink Replacement (Trained Technicians Only); Remove a Processor and Heat Sink

1. Ensure that PCIe adapter installation meets the rules in “PCIe slots and adapters” on page 65.
2. The procedure for installing a PCIe adapter is similar for different types of riser assembly. In
this topic, the LP-FH riser assembly is used as an example.
Step 3. Connect cables to the PCIe adapter in the riser assembly. See
Internal Cable Routing Guide.
After you finish
1. Reinstall the riser assembly. See
“Install a rear riser card” on page 257.
2. Complete the parts replacement. See
“Complete the parts replacement” on page 288.
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.
Attention: Before you begin replacing a processor, make sure that you have an alcohol cleaning pad (part
number 00MP352) and thermal grease.
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.
Note: This section is for processor and heat sink replacement. For the replacement of the Processor
