8.7.4 Power On and Off, Reset, and Halt
The SCM power {on, off}, halt {in, out}, and reset commands perform
the same functions as the buttons on the control panel.
PowerOnandPowerOff
The SCM power on command powers the system on, and the power off
command powers the system off. The Power button on the control panel,
however, has precedence.
• If the system has been powered off with the Power button, the SCM cannot
power the system on. If you enter the power on command, the message
“Power button is OFF” is displayed, indicating that the command will have
no effect.
• If the system has been powered on with the Power button, and the power
off command is used to turn the system off, you can toggle the Power
button to power the system back on.
