Processor installation guidelines

Observe the following important guidelines before performing any of the installation steps listed in the next
section:
The processor 1 socket (U42) must always be populated. If no processor is installed in this socket, the
system fails to boot, halts during POST, and does not function properly.
Handle the processor and heat sink with care. Damage to either may affect processor performance.
The processor socket pins are very fragile. Do not bend or damage them.
Be sure that the server has the most recent ROM version. If the ROM is not the most recent version, failure to
flash the ROM before installing a processor can cause a system failure.
HP does not recommend using a processor in the processor 2 socket (U55) when all processor 2 socket
DIMM slots (DIMM5 to DIMM8) are empty. Populate at least the DIMM7 and DIMM8 slots when you install
a second processor.
CAUTION: To prevent the heat sink from tilting to one side during installation or removal procedures, HP
recommends that you alternate tightening or loosening each screw a little at a time. Do not tighten or
loosen one screw completely before tightening or loosening the other.
CAUTION: To help avoid damage to the processor and system board, do not install the processor without
using the processor installation tool.
NOTE: The heat sink may differ slightly in appearance from the design shown in this document. This does not
affect the installation or removal procedures.
