Refer to "Table 1. 2 MODE switch and Function" below regarding the differences between the various operating modes.

[Table 1. 2 MODE switch and Function]

Mode	POWER switch		Console
	Shut Down Process	Power On	STOP-A
MANUAL or MAINTENANCE	Yes	Yes (Stops in OpenBoot)	Enters OpenBoot
AUTO	Yes	Yes (Solaris OS automatically starts up)	Enters OpenBoot
UNLOCK	Yes	Yes (Stops in OpenBoot)	Enters OpenBoot
SECURE or LOCK	No	No (After the power of system is turned on, Solaris OS automatically starts up)	Ignored

The system was designed to run with the MODE switch set to SECURE/LOCK in the majority of situations.
Setting it to SECURE/LOCK offers safer operation than AUTO/UNLOCK, as it protects against improper use of controls on the operation panel.

For example, if the MODE switch is set to AUTO, Solaris OS automatically starts up. However, when the MODE Switch is set to SECURE or LOCK, the system cannot be booted up or shutdown by pressing the POWER Switch.
When the mode switch is SECURE or LOCK, the POWER switch cannot be operated. Switch the mode as necessary.

MANUAL/MAINTENANCE/UNLOCK should only be used when performing maintenance and related work on the system. It should not be used during normal operation. Turning on the system when the MODE switch is set to MANUAL/MAINTENANCE/UNLOCK will stop it in the OBP (OpenBoot PROM) state without booting up Solaris OS.

Normally, you can enter the OpenBoot environment when STOP-A is entered on the console while Solaris OS is running. On a tty console, the Break operation is equivalent to STOP-A. It is possible to enter the OpenBoot environment only when the MODE switch is set to MANUAL, MAINTENANCE, AUTO or UNLOCK. You cannot enter the OpenBoot environment when the MODE switch is set to SECURE/LOCK.

The POWER switch only works when the MODE switch is set to MANUAL, MAINTENANCE, AUTO or UNLOCK. It will not work when the MODE switch is set to SECURE/LOCK.

You can display the current MODE switch setting with the command fjprtdiag -v.
