Overview
The Power over Ethernet Injector provides data and AC power through the
Ethernet cable to PoE-equipped device, such as AP, PoE splitter or other
equipment support IEEE 802.3af standard. The injector supports IEEE
802.3af standard that can detect the connected device, which supports
the IEEE 802.3af and then provide the power to the device. If the injector
detects that the connected device does not support the IEEE 802.3af,
then the injector will not provide the power to the connected device. The
injector is typically installed near the Ethernet hub. The following figures
show the example applications of the Power over Ethernet Injector.
