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 "Memory module installation rules" on page 81. 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 75. 4. Remove the cooling shroud. See "Removing and reinstalling the cooling shroud" on page 79. 5. Remove the heat sink.
