Supplying dual power
If the appliance is provided with both PoE and 12 V dc power, PoE has priority over the 12 V dc input. In this case, the appliance draws all of its current from PoE. If you disconnect the Ethernet 1 cable, or if the PoE source (injector or Ethernet switch) has a failure or a power outage, the appliance falls back automatically and transparently to the 12 V dc input. If PoE is restored, the appliance switches automatically and transparently back to PoE power.

Grounding the appliance
You must mount the appliance on a grounded metal surface. Alternatively, you can connect a ground wire to one of the mounting screws.
