Removing a microprocessor and heat sink

Attention:

vDo 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.

vDropping the microprocessor during installation or removal can damage the contacts.

vDo not touch the microprocessor contacts; handle the microprocessor by the edges only. Contaminants on the microprocessor contacts, such as oil from your skin, can cause connection failures between the contacts and the socket.

To remove a microprocessor and heat sink, complete the following steps:

1.Read the safety information that begins on page vii, “Handling static-sensitive devices” on page 35, and “Installation guidelines” on page 33.

2.Turn off the server and peripheral devices and disconnect the power cord and all external cables.
