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.

Hardware Description
The Power over Ethernet Injector has three connection ports and one LED
indicator. We will describe each in following.
Data In port: It is an RJ-45 Ethernet interface port for data
transmitting into the PoE Injector. It is for connecting with the switch.
Power In port: The Power In port is for supplying the power into the
Injector.

Installation
To install the Power over Ethernet Injector, please follow the steps below.
1. Use RJ-45 cable to connect the Data in port of the Power over
Ethernet Injector to Switch/HUB.
2. Use RJ-45 cable to connect the Data out port of the Power over
Ethernet Injector to PoE Splitter, PD (Such as Router, Access
Point…etc.) or PoE Hub.
3. Plug in the power cord of the Power over Ethernet Injector to the wall
power plug.
4. Before starting, make sure all connections are correct.
The Power over Ethernet Injector connects to the Splitter, POE
Hub or PD via Data Out port.
The Power over Ethernet Injector connects to the switch/hub via
Data In port.
The Power In port is to get the power supply for Power over
Ethernet Injector from wall power plug.
