treatment, recovery and recycling techniques to ensure
human health and high environmental protection. Your
product is designed and manufactured with high quality
materials and components, which can be recycled and
reused. Do not dispose of your old product in your
general household waste bin. Inform yourself about the
local separate collection system for
electrical and electronic products
marked by this symbol:

Use one of the following disposal options :

1. Dispose of the complete product (including its cables,
plugs and accessories) in designated WEEE collection
facilities.

2. If you purchase a replacement product, hand your

Background

The PoE Extender can be used for installations that require
distances of more then 100 meters (328 feet) between the data
switch to the powered device.

100m -> WLAN AP

3BFunctions and Features

♦ Extends power and data range for up to 600 meters
with no need for an additional power source.
♦ Compatible with all Microsemi Midspans and

802.3af/802.3at PSEs.
♦ Can extend IEEE 802.3at PD range to 200 meters
when connected to Microsemi 95xx series (4-pair IEEE

802.3at)

♦ Supports 10/100/1000 mbps data rates
♦ Plug and Play; no configuration required during

installation.

4BPD-PoE Extender EMC Compliance:

♦ FCC Part 15 and EN55022
♦ EN55024
♦ VCCI

Troubleshooting

Symptom

Corrective Steps

Extender
does not
power up

1. Verify that the input port of the
PoE extender is connected to an
active IEEE 803.af/at PSE
equipment.

The PD
does not
operate

1. Verify that the extender is
powered up.

2. Verify that the Extender detects a
PD.

3. Verify that the PD is designed for
IEEE 802.3 af/at operation.

4. Verify that you are using a
standard Category 5/5e/6, straight­wired cable, with four pairs.

5. If an external power splitter is in
use, replace it with a known, good
splitter.

6. Verify that the PD is connected
to the Data & Power output port.

7. Try to reconnect the same PD
into a different Extender. If it works,
there is probably a faulty port or
RJ45 connection.

8. Verify that there is no short over
any of the twisted pair cables or

over the RJ45 connectors.

The end

device
operates,
but there
is no data
link

1. Verify that for this link, you are

using standard UTP/FTP Category
5/5e/6 straight (non-crossover)
cabling, with all four pairs.

2. Verify that the Ethernet cable
length is less than 100 meters from
the Ethernet source to the
load/remote terminal.

3. Try to reconnect the same PD
into a different Extender. If it works,
there is probably a faulty port or
RJ45 connection.

4. If an external power splitter is in
use, replace it with a known-good

splitter.

5BWARNING

♦ Read the installation instructions before connecting
the PoE Extender to the PSE.
♦ A voltage mismatch can cause equipment damage
and may pose a fire hazard. If the voltage indicated on the
label is different from the power outlet voltage, do not
connect the PoE Extender to the power outlet.
♦ The unit is indoor rated.

6BPreliminary Step s

♦ The PoE Extender can be placed on a rack, wall or

desktop.

Before placing the PoE Extender:

♦ Do not cover the PoE Extender. Keep the PoE Extender

away from excessive heat and humidity and free from
vibration.

♦ Use a splitter if desired; ensure that the splitter is

connected close to the PD terminal and not on the
Extender.

♦ No “on-off” switch exists; simply plug the Cat5e

Ethernet cable from the PSE device (PoE switch or
Midspan) to the Extender PoE input (RJ45 connector).

♦ Extender PoE output (the RJ45 connector) should be

connected to the PD terminal using a Cat5e Ethernet
cable.

7BInstalling the Unit

1. Connect the PoE input port to a PSE (Midspan or Switch).

2. Connect the PoE output port to a PD (IP Phone, WLAN AP,
IP Camera, and so on).

3. Verify that the unit LEDs are on.
