Base Module

2.4.6.2.DN (Shut down System Power)

m	b	u
X

*The command is executable to the active partition (after automatic system boot/UP command execution).

Function:

This command is used to shut down the system DC power.

It shuts down the system DC power only if the software is not running (not in S0 state).

If the system software (OS or BIOS) is running (S0 state), this command only reports a Power Button interrupt to the software. The interrupt service depends on the software (the software may ignore the interrupt or perform a shut-down).

The software may not be able to service the power button interrupt due to stall or other cause even if the iSP recognizes that the software is running. In this case use the DF command to force a system power shut-down.
