POE Injection Cable – male DC & male RJ45 to female RJ45 Power over Ethernet Adapter – 12 volt to 57 volt
Passive PoE is a simple way of providing power to an access point which is not located near a power adapter and which supports Power over Ethernet. Passive PoE uses free wires in the Ethernet / Network cable and sends the equipments power along them to the far end. Over a short distance, it is usually possible to use the power adapter supplied as standard with the access point. If the loss of the voltage on the wiring along longer lengths of Ethernet cable is too high, it is possible to use a more powerful power adapter, to eliminate the loss of voltage.
