Lenovo 1047 - Manual (Page 81)

This section provides instructions on how to install the microprocessor.
CAUTION:
The heat sink and microprocessor might be very hot. Turn off the server and wait three to five minutes
to let the server cool before removing the server cover.
For optimal performance, follow these microprocessor installation rules:
1. When two microprocessors are installed, both must have the same core voltage and core speed.
2. When only one microprocessor is installed, it must be in the socket labeled CPU0. The other socket
must be kept empty.
3. Always install the microprocessor first into the CPU0 socket, and then install another microprocessor
into the CPU1 socket if you want to install two microprocessors.
To install 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. Remove the server cover. See “Removing the server cover” on page 21.
3. Remove the microprocessor fan duct. See Removing the microprocessor fan duct.
4. Remove the heat sink. See Removing the heat sink.
5. Press down and push the small handle outward on the microprocessor socket to lift the handle to
the open position.
