Recycling and Disposal

Disposal instructions for old products. The WEEE
(Waste Electrical and Electronic Equipment)
national environmental initiatives has been put
in place to ensure that products are recycled
using best available treatment, and 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 the
designated WEEE collection facilities.

2. If you purchase a replacement product,
return your older product (including all
components) back to the retailer. The retailer
should accept it as required by the national
WEEE legislation.

Note: Unless otherwise noted, references to the
PD-3501G/AC in this document refer to both the PD-3501/AC
and the PD-3501G/AC.

Safety Information
Important Safety Information

 The PD-3501G should be connected to PoE networks

only, without routing to the outside plant.

 Only qualified personnel can install or remove the

PD-3501G.

 AC Power Cord Set:

 The power cord must have regulatory agency approval for

the specific country in which it is used (for example UL,
CSA, VDE, etc.).

 The power cord must be a three-conductor type (two

current carrying conductors; one ground conductor)
terminated on one end by an IEC 60320 appliance coupler
(for connection to the PD-3501G), and on the other end by
a plug containing a ground (earthing) contact.

 The power cord must be rated for a minimum of 250 VAC

RMS operation, with a minimum rated current capacity of
5 amps (or a minimum wire gauge of 18 AWG (0.75 mm2).

: A PD-3501G installed in Australia requires power cords

with a minimum wire gauge of 16 AWG (1.0 mm2).

: The PD-3501G "DATA IN" and "DATA & POWER OUT"
ports are shielded RJ45 data sockets. They cannot be used as
Plain Old Telephone Service (POTS) telephone sockets. Only
RJ45 data connectors can be connected to these sockets.

 The AC wall socket-outlet must be near the PD-3501G

and easily accessible. You can remove AC power from
the PD-3501G by disconnecting the AC power cord from
either the wall socket-outlet or the PD-3501G appliance
coupler.

 The PD-3501G DATA IN and DATA & POWER OUT

interfaces are qualified as Safety Extra-Low Voltage
(SELV) circuits according to IEC 60950-1. These
interfaces can only be connected to SELV interfaces on
other equipment.

WARNINGS!

 The PD-3501G should only be connected to the IP

device with which it was bought. Using the PD-3501G
with other IP devices can cause damage to the IP
device.

 Read the installation instructions before connecting the

PD-3501G to its power source.

 Follow basic electricity safety measures whenever

connecting the PD-3501G to its power source.

 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 PD-3501G to this power outlet.

 The unit can be used only in Restricted Access

Locations.

Troubleshooting

Symptom

Corrective Steps

PD-3501G
does not
power up

1. Verify that a reliable power cord
is used.

2. Verify that the voltage at the
power inlet is between 100 and 240
VAC.

3. Remove and re-apply power to
the device and check the indicators
during power up sequence.

The PD
does not
operate

1. Verify that the PD-3501G detects
a PD.

2. Verify that the PD is designed for
PoE operation.

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

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

5. Ensure input Ethernet cable is
connected to the DATA IN port.

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

7. Try to reconnect the same PD
into a different PD-3501G. 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 the port indicator on
the front panel is continuously lit.

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

3. Verify that for this link, you are
using standard UTP/FTP Category 5
straight (non-crossover) cabling,
with all four pairs.

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

5. Try to reconnect the same PD
into a different PD-3501G. If it
works, there is probably a faulty port
or RJ45 connection.

Functions and Features

The PD-3501G Power over Ethernet (PoE) is a Single Port
Midspan that offers a compact and cost effective power solution
for IP phones, WLAN access points, network cameras and other
IP terminal installations.
The PD-3501G converts AC power to 48VDC power is then
provided over the Ethernet cable.
The PD-3501 supports 10/100 Mbps pass through
data rates while the PD-3501G supports up to
Mbps pass through data rates.
The single port PD-3501G can be powered via universal
AC input.

PD-3501G EMC Compliance:

 FCC Part 15 class B and EN55022 class B
 EN55024
 VCCI

PD-3501G Safety Compliance:

 UL/cUL per 60950-1 2nd Ed.
 GS mark

Preliminary Steps

 Ensure that AC power is applied to the PD-3501G,

using an operational AC cable with an appropriate
ground connection.

 Ensure that output Ethernet cable is connected to the

DATA & POWER OUT port.

 Verify that power ready Ethernet compatible device is

connected.

WARNING
Do not use cross over cable between the PD-3501G output
port and the load device
Installation

The PD-3501G can be placed on a desktop.

: Before placing the PD-3501G:

 Do not to cover PD-3501G or block the airflow to the

PoE with any foreign objects. Keep the PD-3501G away
from excessive heat and humidity and free from
vibration and dust.

 Ensure that the cable length from Ethernet network

source to the terminal does not exceed 100 meters
(330 feet). The PoE is not a repeater and does not
amplify the Ethernet data signal.

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

connected close to the terminal and not on the
PD-3501G!

 No “on-off” switch exists; simply plug the PD-3501G into

an AC power source.

Installing the Unit

Refer to Figure 1.

1. Connect the PD-3501G to an AC outlet (100 - 240VAC), using
a standard power cord.

2. Connect the DATA IN jack (input) to the remote Ethernet
network switch's Patch panel and the DATA & POWER OUT jack

(output) to the terminal.
