Processor and heat sink replacement
Use this information to remove and install a processor and heat sink.
The server supports the second-generation AMD ® EPYC TM family of processors.
The server supports three types of heat sinks. Depending on the specific type, the heat sink on your server
might be different from that shown in the illustrations. For detailed information on heat sink selection, see
“Technical rules for processor and heat sink” on page 135.
CAUTION:
Make sure that all server power cords are disconnected from their power sources before performing
this procedure.
Attention:
• Each processor socket must always contain a cover or a processor and heat sink. When removing or
installing a processor and heat sink, protect empty processor sockets with a cover.
• Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and
easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause
connection failures.
• Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact
with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage
components, such as electrical connectors in the processor socket. Do not remove the grease cover from
a heat sink until you are instructed to do so.
