Chapter 3 Maintaining the Server
Installing or Replacing Server Components
Additional CPU-Related Parts to Order with RMA Replacement Motherboards
When a return material authorization (RMA) of the motherboard or CPU is done on a Cisco UCS
C-series server, additional parts might not be included with the CPU or motherboard spare bill of
materials (BOM). The TAC engineer might need to add the additional parts to the RMA to help ensure
a successful replacement.
Note This server uses the new independent loading mechanism (ILM) CPU sockets, so no Pick-and-Place
tools are required for CPU handling or installation. Always grasp the plastic frame on the CPU when
handling.
• Scenario 1—You are reusing the existing heatsinks:
–
Heat sink cleaning kit (UCSX-HSCK=)
– Thermal grease kit for C240 M4 (UCS-CPU-GREASE3=)
•
Scenario 2—You are replacing the existing heatsinks:
– Heat sink (UCSC-HS-C240M4=)
– Heat sink cleaning kit (UCSX-HSCK=)
A CPU heatsink cleaning kit is good for up to four CPU and heatsink cleanings. The cleaning kit contains
two bottles of solution, one to clean the CPU and heatsink of old thermal interface material and the other
to prepare the surface of the heatsink.
New heatsink spares come with a pre-applied pad of thermal grease. It is important to clean the old
thermal grease off of the CPU prior to installing the heatsinks. Therefore, when you are ordering new
heatsinks, you must order the heatsink cleaning kit.
