Lenovo RD430 - Manual (Page 152)

Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• Ensure that the new microprocessor is the correct type your server supports. See “Features” on page 8.
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
topic.
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.
3. Remove the server cover. See “Removing the server cover” on page 83.
4. Remove the cooling shroud. See “Removing and reinstalling the cooling shroud” on page 91.
5. Remove the heat sink. See “Installing or replacing a heat sink” on page 133.
6. Gently press down the small handle on the microprocessor socket and then pull the handle a little bit
outward to release it from the secured position. Then, pivot the handle upward to the fully open position.
Then, gently press the microprocessor retainer to open it.
