Replacing the processor and
heatsink
Notes:
• Always connect the power cord last and always remove it before
adding, removing or changing any hardware components. Make
sure that you install the processor into the CPU socket before you
install the CPU heatsink.
• If you buy a CPU separately, make sure that you use an Intel-
certified multidirectional heatsink and fan only.
• Make sure to install the serverboard into the chassis before you
install the CPU heatsinks.
• When receiving a serverboard without a processor pre-installed,
make sure that the plastic CPU socket cap is in place and none of
the socket pins is bent; otherwise, contact your retailer
immediately.
Removing the heatsink
Warning! We do not recommend that the CPU or the heatsink be
removed. However, if you do need to uninstall the heatsink,
please follow the instructions below to prevent damage to the
CPU or the CPU socket.
1 Remove power from the system and unplug the AC power cord
from the power supply.
2 Disconnect the heatsink fan wires from the CPU fan header.
