CAUTION: The socket pins are fragile and can be permanently damaged. Be careful not to bend the pins in the
socket when removing the processor out of the socket.
11. Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new
processor.
NOTE: If you are permanently removing a processor, you must install a processor/DIMM blank in the vacant socket
to ensure proper system cooling. The processor/DIMM blank covers the vacant sockets for the DIMMs and the
processor.
