Dn (Shut Down System Power) - NEC 1080Xd User Manual

DN (Shut Down System Power)

Execution:
This command can be executed on a partition if Automatic startup has completed or the
UP command has been executed. (The partition is in the DC POWER ON state.)
Function:
This command turns off system power (DC).
If software is not running (for example, in the S0 state), this command turns off the
system.
If any software, such as the OS and BIOS, is running (for example, in the S0 state), this
command only reports a power button interrupt to the software, and the process for the
power button interrupt depends on the software. (The software may ignore the power
button interrupt, or may perform a shutdown and turn off the power.)
Even if the iSP recognizes that some software is running, the software may not be able
to process the power button interrupt due to stalling. In this case, use the DF command
to force the system to turn off.
Note:
Maintenance mode.
