Videon devices support both DC power and Power over Ethernet (PoE). Understanding how the device behaves when both power sources are connected can help you plan for redundancy and avoid unexpected reboots.
Note: This article only applies to Max 2, Max, and Node products.
Power Priority
Videon devices prioritize DC wall power whenever it is available.
Behavior by Connection Order
If DC is connected first
When PoE is connected after DC, the device continues operating on DC power
If DC power is removed, the device will reboot and then switch to PoE
If PoE is removed, the device remains powered on DC without interruption
If PoE is connected first
When DC is connected after PoE, the device initially runs on PoE and then switches to DC
If DC power is removed after switching, the device will reboot and then switch back to PoE
If PoE is removed after switching to DC, the device remains powered on DC without interruption
Important Note
Since the devices prioritize DC power in all cases, a reboot will occur if the active DC wall power source is removed, and the device falls back to PoE
