Replacing CPUs and Heatsinks

The server supports up to four EP-Series CPUs. See Figure 3-13 on page 3-22for the CPU socket numbering.

The minimum configuration is two CPUs (CPU1 and CPU2).

The server must have either two or four CPUs to operate; you should populate CPU1 and CPU2 first, and then populate CPU3 and CPU4.

This section contains the following topics:

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, there are additional parts that 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.

Scenario 1—You are re-using the existing heatsinks:

Heat sink cleaning kit (UCSX-HSCK=)

Thermal grease kit for C420 (UCS-CPU-GREASE=)

Intel CPU Pick-n-Place tool for EP CPUs (UCS-CPU-EP-PNP=)

Scenario 2—You are replacing the existing heatsinks:

Heat sink (UCSC-HS-C420M3=)

Heat sink cleaning kit (UCSX-HSCK=)

Intel CPU Pick-n-Place tool for EP CPUs (UCS-CPU-EP-PNP=)

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 ordering new heatsinks it is still necessary to order the heatsink cleaning kit at a minimum.
