System Control Keyswitch Settings
Name Description
Normal This setting enables the system Power button to power the
system on or off.
Locked This setting disables the system Power button to prevent
unauthorized users from powering the system on or off. It also
disables the keyboard L1-A (Stop-A) command, terminal Break
key command, and ~# tip window command, preventing
users from suspending system operation to access the system
ok prompt.
The Locked setting, used for normal day-to-day operations,
also prevents unauthorized programming of the system boot
PROM firmware.
Diagnostics This setting forces the power-on self-test (POST) and
OpenBoot Diagnostics tests to run during system startup and
system resets. The Power button functions the same as when
the system control keyswitch is in the Normal position.
Standby This setting forces the system to power off immediately and to
enter standby mode. It also disables the Power button. You
might want to use this setting when AC power is interrupted
and you do not want the system to restart automatically when
power is restored. With the system control keyswitch in any
other position, if the system were running prior to losing
power, it restarts automatically once power is restored.
The Standby setting also prevents an ALOM console from
restarting the system. However, the ALOM card continues to
operate using the system's standby power.
