Installing an additional microprocessor and heat sink

The following notes describe the type of microprocessor that the server supports and other information that
you must consider when you install a microprocessor and heat sink.
• Microprocessors are to be installed only by trained technicians.
Important: Always use the microprocessor installation tool to install a microprocessor. Failing to use
the microprocessor installation tool may damage the microprocessor sockets on the system board. Any
damage to the microprocessor sockets may require replacing the system board.
• Be extremely careful, the microprocessor socket contacts are very fragile. Do not touch the
microprocessor socket contacts. Contaminants on the microprocessor contacts or microprocessor socket
contacts, such as oil from your skin, can cause connection failures between the contacts and the socket.
• Do not allow the thermal grease on the microprocessor and heat sink to come in contact with anything.
Contact with any surface can contaminate the thermal grease and the microprocessor socket.
• Do not use any tools or sharp objects to lift the locking levers on the microprocessor socket. Doing so
might result in permanent damage to the system board.
• Each microprocessor socket must always contain either a socket cover or a microprocessor and heat sink.
• Be sure to use only the installation tools provided with the new microprocessor to remove or install
the microprocessor. Do not use any other tool.
• When installing multiple microprocessors, open one microprocessor socket at a time to avoid damaging
other microprocessor socket contacts.
