This function requires hardware support and the related commands need to be executed.

Hardware requirement: The PAIB board with the PMUA daughter board must be used.

The commands are executed as follows:

Run the display emu command to query the environment monitoring unit (EMU) currently configured on the MA561x.
Run the emu add command to add the PMU as an EMU.
Run the interface emu command to enter the PMU mode.
Run the broad-service power-off shutdown command to enable the function of automatically cutting off the power supply.
Run the display power system parameter command to query and confirm that the function of automatically cutting off the power supply is enabled. That is, Power-cut-close-Broad-service is On.
After the preceding commands are executed, if no mains supply is input, an external battery is used for supplying power. In this case, the device automatically cuts off the power supplied to the broadband service board to enable the voice board works normally. This prolongs the backup time of the battery.
