CAUTION
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.
Dropping the microprocessor during installation or removal can damage the contacts.
Do 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.
Use the microprocessor installation tool that came with the new microprocessor to remove
the microprocessor from the server.
To remove a microprocessor and heat sink, complete the following steps:
Step 1
Read the safety information, “Handling static-sensitive devices”, and “Installation
guidelines”.
Step 2
Turn off the server and peripheral devices and disconnect the power cord and all external
cables.
Step 3
Remove the top cover (see “Removing the top cover”).
Step 4
Remove the top cover bracket (see “Removing the top-cover bracket”).
Step 5
Rotate the heat-sink release lever
to the fully open position.
