v If you are adding Intel Xeon MP microprocessors, populate the empty
microprocessor sockets in numeric order, starting with socket 1. If you install the
microprocessors in the wrong order, the server will not start.
Attention: You must make sure that the locking lever on the microprocessor
socket is in the fully open position before you insert the microprocessor in the
socket. Failure to do so might result in permanent damage to the microprocessor,
microprocessor socket, and system board. See Figure 44 on page 49.
v Always install the heat sink that comes with the microprocessor.
v Server models that come with Intel Xeon DP microprocessors support a
maximum of two microprocessors per SMP Expansion Module, installed in
microprocessor sockets 1 and 4.
v Intel Xeon DP microprocessors are supported in microprocessor sockets 1 and 4
only. Intel Xeon MP microprocessors are supported in microprocessor sockets 1,
2, 3, and 4.Figure 42 shows the location of the startup microprocessor and its
VRM on the system board. It also shows the microprocessor baffles and the
VRM slots for the other microprocessor sockets.

Complete the following steps to install a microprocessor:
1. Read the safety information beginning on page v and "Installation guidelines"
on page 9.
2. Turn off the server and peripheral devices, disconnect the power cords, and
disconnect all external cables from the SMP Expansion Module.
3. Pull out on the quick release latches on each side of the server; then, pull the
server out of its rack enclosure until it stops.
4. Open the top cover.
5. If necessary, remove the SMP baffle or top SMP Expansion Module.
