2.12 Power Switch
The front panel Power Switch controls AC Power input to the unit. If the
optional DC input is provided with 24V, or a valid DC supply, the unit will
operate. In other words, if the front panel switch will not remove power if the
optional DC input is powered.
The AC and DC input option provides a redundant and automatic backup source
in the case of failure of either input.
