SUPPLEMENTAL MATERIAL

Air Baffle Replacement Kit

Air baffles are designed to direct airflow through the server to maintain server temperature at a safe
operating level. These baffles must always remain installed during server operation. The Air Baffle
Replacement Kit includes the air baffles needed for one UCS C220 M4 server.

CPU Heat Sink Cleaning Kit

The cleaning kit is used to remove the existing thermal compound from the bottom of the heat sink during
a CPU replacement process. Instructions for cleaning are found at the following link:

See the section titled “Replacing CPUs and Heatsinks.”

CAUTION: Use only the thermal grease specified for this server
(UCS-CPU-GREASE3=). This thermal grease comes in a white-tipped
syringe and is to be used only in the C220 M4 and C240 M4 servers. Other
servers use thermal grease in a blue-tipped syringe (UCS-CPU-GREASE=).

Thermal grease for other systems may have different thermal
conductivity properties and may cause overheating if used in the C220 M4
or C240 M4 servers.

DO NOT use thermal grease available for purchase at any commercial
electronics store. If these instructions are not followed, the CPU may
overheat and be destroyed.

NOTE: When you purchase a spare CPU, the thermal grease with syringe applicator
is included.
