EKI-2701HPI-AE User Manual 6
2.1 Front Panel
On the front panel the Power over Ethernet Injector is equipped with two RJ-45 ports
and three LED indicators.
 LAN port: It is an ordinary RJ-45 Ethernet port for data transmitting and receiv-
ing.
 PoE port: It is an RJ-45 Ethernet port capable of supplying power over the
Ethernet cable as well as forwarding data to powered devices.
 P1 & P2: The indicators light up when their respective power inputs are active.
 PoE: This LED indicator lights up while power feeding works normally.
2.2 Top View
Designed with two power inputs, the PoE Injector allows users to supply redundant
power rating in the range of 24 to 48V.
2.3 Grounding the PoE Injector
Follow the instructions below to attach the PoE Injector to ground.
1. On the top of the device, locate and remove the dome screw which has a
ground symbol beside it.
2. Attach the ground wire to the screw hole with the dome screw.
2.4 Wiring the Power Inputs
Please follow the steps below to wire power lines from the terminal block to the com-
pliant external DC power source.
1. Before wiring, make sure the power source is disconnected.
2. Using the wire-stripping tool, strip a short piece of insulation from the output
wires of the DC power source.
3. Identify the positive and negative feed positions for the terminal block connec-
tion. See the symbols printed on the panel indicating the polarities and DC input
power range in voltage.
Plugs for Power 1 & Power 2
4. Insert the exposed wires into the terminal block plugs. Only wires with insulation
should extend from the terminal block plugs. Note that the polarities between
the wires and the terminal block plugs must be positive to positive and negative
to negative.
5. Use a slotted screwdriver to tighten the captive screws.
Caution! When installing the PoE Injector, the ground connection must always be
made first and disconnected last.
