Microprocessor and heat sink

Before you begin:
v Read the "Installation guidelines" on page 25.
v Read Appendix B, "Safety information," on page 143.
v Review the information in "System reliability guidelines" on page 25.
To remove the microprocessor and heat sink, complete the following steps.
1. Turn off the server and remove external cables.
2. Remove the side cover (see "Removing the side cover" on page 28).
3. Remove the frame-support bracket (see "Removing and installing the support
4. Disconnect any cables that impede access to the microprocessor.

a. Press the microprocessor-baffle release lever down, move it toward the
other microprocessor, and lift it up to the open position.
b. Slide the heat-sink assembly toward the front of the server and tip the rear
flange out of the heat-sink socket.
c. Lift the heat sink up and out of the server.
Note: It might be necessary to gently twist the heat sink to loosen it from
the microprocessor.
Important: Be careful when handling the microprocessor and heat sink. If
the thermal grease between the microprocessor and heat sink
will be reused, do not contaminate it. If replacement thermal
grease is provided with the replacement part, be sure to remove
all traces of existing thermal grease from the remaining part
before applying the new thermal grease.
