Turn off the server,
and disconnect the power cords before moving any jumpers
Be sure the microprocessor bus-to-core
fraction is set correctly.
For example, if you have a 350 MHz microprocessor
installed and the system bus speed is 100 MHz (the default), be sure that
the jumpers are set to a bus-to-core fraction of 3.5 (350/100).
Refer to jumpers J27-J30 in the Core/Bus Ratio table below.
If installing or changing to a
different speed processor than the original processor,
be sure to change the processor core-frequency selection jumpers on the processor board.
If the microprocessor bus-to-core fraction (see below Core/Bus Ratio table
) is incorrect, system board components will overheat and component
damage might occur..
