Additional CPU-Related Parts to Order with RMA Replacement CPUs
When a return material authorization (RMA) of the CPU is done on a Cisco UCS C-Series server, additional
parts might not be included with the CPU spare. The TAC engineer might need to add the additional parts to
the RMA to help ensure a successful replacement.
The following items apply to CPU replacement scenarios. If you are replacing a system chassis and moving
existing CPUs to the new motherboard, you do not have to separate the heatsink from the CPU. See Additional
CPU-Related Parts to Order with RMA Replacement System Chassis, on page 32.
Note
• Scenario 1—You are reusing the existing heatsinks:
• Heatsink cleaning kit (UCSX-HSCK=)
One cleaning kit can clean up to four CPUs.
• Thermal interface material (TIM) kit for M5 servers (UCS-CPU-TIM=)
One TIM kit covers one CPU.
• Scenario 2—You are replacing the existing heatsinks:
Use only the correct heatsink for your CPUs to ensure proper cooling. There are
two different heatsinks: UCSC-HS-C220M5= for CPUs 150 W and less;
UCSC-HS2-C220M5= for CPUs above 150 W.
Caution
• Heatsink: UCSC-HS-C220M5= for CPUs 150 W and less; UCSC-HS2-C220M5= for CPUs above
150 W
New heatsinks have a pre-applied pad of TIM.
• Heatsink cleaning kit (UCSX-HSCK=)
One cleaning kit can clean up to four CPUs.
• Scenario 3—You have a damaged CPU carrier (the plastic frame around the CPU):
• CPU Carrier: UCS-M5-CPU-CAR=
• #1 flat-head screwdriver (for separating the CPU from the heatsink)
• Heatsink cleaning kit (UCSX-HSCK=)
One cleaning kit can clean up to four CPUs.
• Thermal interface material (TIM) kit for M5 servers (UCS-CPU-TIM=)
One TIM kit covers one CPU.
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 TIM and the other to prepare the surface of
the heatsink.
