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.
This server uses the new independent loading mechanism (ILM) CPU sockets, so no Pick-and-Place
Note
tools are required for CPU handling or installation. Always grasp the plastic frame on the CPU when
handling.

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 have preinstalled thermal interface material covered by a small sheet of plastic. It
is important to clean the old thermal interface material off of the CPU prior to installing the heatsinks.
Therefore, when you are ordering new heatsinks, you must order the heatsink cleaning kit.
