Installing or replacing a microprocessor

The Model 200 has one microprocessor installed on the system board. If you install
an additional microprocessor to the Model 200, your appliance can operate as a
symmetric multiprocessing (SMP) appliance. This can enhance performance. For
the Model 200, use these instructions to add a microprocessor. The Model 225 has
two microprocessors; use these instructions to replace a microprocessor.
Attention:
install a new or an additional microprocessor, use microprocessors that have the
same cache size and type, and the same clock speed. Microprocessor internal
clock frequencies and external clock frequencies must be identical.
