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 support the
IEEE 802.3af and then provide the power to the device. If the injector detect
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 how Power

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 a RJ-45 Ethernet interface port for data transmit
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.
Data Out port: It is a RJ-45 Ethernet port to connect with PoE Splitter,
or PD.

Installation
To install the Power over Ethernet Injector, please follow the steps below.
1. Using RJ-45 cable that is Data in port on the Power over Ethernet
Injector to connect with the Switch/HUB.
2. Using RJ-45 cable that is on the Data out port in Power over Ethernet
Injector to connect with the 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 is in Data Out port.
The Power over Ethernet Injector connects to the switch with
Data In port.
The Power In port is to get the power supply to Power over
Ethernet Injector from wall power plug.
