(CrossPoint 450 Plus and MAV Plus 2412, 2424, 3216, and 3232 switchers only)
Includes two internal 100 VAC to 240 VAC, 50/60 Hz, switching power
supplies, which provide worldwide power compatibility.
The power supply circuitry is configured to automatically switch over from
the primary supply to the hot redundant supply in the case of a failure.
The hot redundant power supply means high reliability for the system and
no loss of functionality should the primary supply fail; the redundant power
supply immediately assumes the load.
Power supply status LEDs —

Front panel LEDs indicate the status of the primary and redundant power
supplies.
