System Board Switches
Processor Board Bus/Core Frequency Ratio Switch
Settings
Processor board bus/core frequency ratio switches can be set manually or by
the system BIOS. Figure D-11 shows the location of the processor board
bus/core frequency ratio switches. Table D-5 shows the bus/core frequency
ratio switch settings.
IMPORTANT: The bus/core switches come set at the Off position. This allows the ROM to
automatically set the optimal speed for the buses. The server will not start if the switches
are set to a speed higher than the slowest processor.
