Switch Description
SW1-1
Switches 1, 2, 3, and 4 in combination specify the frequency for
the microprocessor. See (below) Microprocessor speed settings.
SW1-2
Switches 1, 2, 3, and 4 in combination specify the frequency for
the microprocessor. See (below) Microprocessor speed settings.
SW1-3
Switches 1, 2, 3, and 4 in combination specify the frequency for
the microprocessor. See (below) Microprocessor speed settings.
SW1-4
Switches 1, 2, 3, and 4 in combination specify the frequency for
the microprocessor. See (below) Microprocessor speed settings.
SW1-5
When On, perform BIOS recovery using boot block (boot block
recovery).
The recovery boot block is in a protected area of flash memory
that cannot be overwritten. When the BIOS becomes corrupted
(for example, if a power failure occurs during a flash update),
the recovery boot block can be used to restore the BIOS.
The code in the recovery block enables the server to start up
and read a flash diskette. The flash utility automatically
recovers the system BIOS from the BIOS recovery files on the
diskette. When the flash is complete, the switch must be moved
to the Off position.
The default setting is Off (disabled).
SW1-6
When On, sets the host bus speed to 66 MHz.
When Off, the host bus speed is 100 MHz.
The default setting is Off (disabled).
SW1-7
Power-On override.
When On, overrides the power-on switch and forces power-On mode.
The system will always boot w/o the use of the power-on switch.
The default setting is Off (disabled).
SW1-8
When On, bypass the power-on password.
When Off, require the user to enter the power-on password at
startup if one is set.
The default setting is Off.
NOTE: If the processor does not react to switch
changes, it is not an error.
Microprocessor Speed Settings SW1-1, SW1-2, SW1-3, SW1-4
NOTE: All microprocessors of speed 450MHz and up
will automatically set their internal speeds, so the switch setting
is not applicable.

Bypassing an Unknown Power-on Password (SW1-8)
When a power-on password is set, POST does not complete
until you enter the password. If you forget the power-on password,
you can regain access to the server through one of the following methods:
(If necessary, see 'Using the Administrator Password Menu' for details.
Start the Configuration/Setup utility programs and change the power-on password.
See 'Using the Power-on Password Menu'
