Attention:
v A startup (boot) microprocessor must always be installed in microprocessor
connector 1 on the system board.
v
To ensure correct server operation, use microprocessors that have the same
cache size and type, front-side bus frequency, and clock speed. Microprocessor
internal and external clock frequencies must be identical.
v
If you are installing a microprocessor that has been removed, make sure that it is
paired with its original heat sink or a new replacement heat sink. Do not reuse a
heat sink from another microprocessor; the thermal grease distribution might be
different and might affect conductivity.
To install a new or replacement microprocessor, complete the following steps. The
following illustration shows how to install microprocessor 2 on the system board.
Note: For simplicity, certain components are not shown in this illustration.

1. Touch the static-protective package containing the microprocessor to any
unpainted metal surface on the server. Then, remove the microprocessor from
the package.
