Power over Ethernet Injector

User Guide

EI-102

1

Overview

The ASUS EI-102 Power over Ethernet (PoE) Injector provides data and

power transmission on a single Ethernet cable. It works together with other

PoE devices such as Access Point (AP), PoE splitter or other equipments

that support IEEE 802.3af standard. The PoE injector detects connected,

IEEE 802.3af compatible devices and provides power to these device; if the

connected device does not support IEEE 802.3af standard, only data flow

could be transmitted. The PoE injector is usually installed near the Ethernet

switch or hub. The following figure shows a PoE network architechture.

Installation

Please follow the steps below to install the PoE Injector:

1. Connect the

Data In

port to an RJ-45 port in your switch or hub via an

Ethernet cable.

2. Connect the

Data Out

port with a PoE Splitter, PD (such as router,

Access Point...etc.) or PoE Hub via an Ethernet cable.

3. Plug the power cord of the PoE Injector to the wall power jack.
