Replacing a microprocessor and heat sink
This information provides instructions on how to replace a microprocessor and heat sink.
To replace a microprocessor and heat sink, complete the following steps:
Attention: When you handle static-sensitive devices, take precautions to avoid damage from static
electricity. For details about handling these devices, see "Handling static-sensitive devices" on page 46.
Notes:
• Use the microprocessor installation tool that came with the new microprocessor kit to remove the
microprocessor from the server.
• Be extremely careful when handling the microprocessor, the microprocessor socket contacts are very
fragile.
• Do not allow the thermal grease on the microprocessor and heat sink to come in contact with anything.
Contact with any surface can compromise the thermal grease and the microprocessor socket.
• Do not touch the microprocessor contacts. Contaminants on the microprocessor contacts, such as oil
from your skin, can cause connection failures between the contacts and the socket.
• Be sure to only install microprocessors that have the same speed, number of cores, and frequency.
• Each microprocessor socket must always contain either a socket cover or a microprocessor and heat
sink.
• Be sure to use only the microprocessor installation tool provided with the new microprocessor to remove
or install the microprocessor. Do not use other tools.
• The microprocessor installation tool has the microprocessor installed on the tool, and might have a
protective cover over the microprocessor. Do not use the tool or remove the cover from the
microprocessor until you are instructed to do so.
• The server supports up to four (per 4U server) Intel Xeon dual-core or quad-core microprocessors (one
microprocessor on each compute book). See
microprocessors.
