• Ensure that the new microprocessor is the correct type your server supports. When two microprocessors
are installed, both must have the same core voltage and core speed.
• Use any documentation that comes with the microprocessor option kit and follow those instructions in
addition to the instructions in this topic.
• Your microprocessor, socket, and socket cover might look slightly different from the illustrations in this
To replace the microprocessor, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the Rack Installation Instructions that comes with the server. If
the server is in tower form factor, lay the server on its side for easier operation.
3. Remove the server cover. See "Removing the server cover" on page 66.
4. Remove the cooling shroud. See "Removing the cooling shroud" on page 69.
5. Remove the heat sink. See "Replacing the heat sink" on page 154.
6. Open the small handle
inward to release it from the secured position. Then, open the other small handle
Note: There are two marks on the microprocessor retainer. Open the small handle marked with
first and then open the other small handle marked with . Always follow the correct sequence when
you open the small handles.
Figure 87. Opening the handles
first by gently pressing down the handle a little bit and then pushing the handle
in the same way.
