Network Configuration Examples

The following illustration shows network configuration examples.

Powering Ethernet Devices

The Power Bridge may be used to power any Ethernet device with
power requirements that are within the specified powering capabilities.

As shown in the previous illustration, the Power Bridge may be used to
power end devices such as IP phones, web cameras, laptop computers,
and others.

IP phones, for example, benefit from Power over LAN in that they no
longer need an external power source connected to wall sockets, which
are unreliable due to the possibility of power interruptions.

Wireless LAN (WLAN) access points may also be enabled to receive
power using the Power Bridge. This can be very effective when
installing WLAN access points or base stations which often require
drawing power from sockets close to the ceiling, where complicated
building codes and standards for power apply.

brackets and six screws, is supplied with the 12-port Power Bridge.

When deciding where to position the Power Bridge, be sure that

•

the Power Bridge is accessible and cables can be connected easily.

•

the ambient room temperature is less than 40°C (104°F); however,
the recommended room temperature is 25°C (77°F) or less.

•

airflow is not restricted around the Power Bridge or through the
vents in the s ide of the Power Bridge. We recomme nd that you
provide a minimum of 25 mm (1 in) clearance around the sides and
back of the Power Bridge, excluding mounting surfaces.

•

water or moisture cannot enter the case of the Power Bridge.

In addition, be sure that cabling is away from

•

sources of electrical noise such as radios, transmitters, and
broadband amplifiers.

Connecting Cables to End Devices

The Power Bridge contains proprietary line sensing capabilities that
enable it to send power only to end devices that are enabled to receive
power. These end devices, termed Power over LAN Enabled, will
receive power once they are connected to the Power Bridge.

The Power Bridge detects devices that are not enabled, and the Power
Bridge will not send power to those devices. Data continue to flo w via
the Category 5, 6, or 6e cabling regardless of the status of the end
device.

End devices that have not been enabled to receive power directly may
receive power and data through an external splitter. The external
splitter separates the power and data prior to connection to the end
device. For more information, see the next illustration.

Before connecting end devices to the Power Bridge, determine if

•

the end device is Power over LAN Enabled. If the end device is not
Power over LAN Enabled, the end device may be safely connected;
however, the port will not supply power and will function as a
normal Ethernet data port.

•

the end device requires an external splitter or only a single RJ-45
connection. If an external splitter is required, be sure to use a
splitter with the correct connector and polarity.

•

the end device’s power requirements are consistent with the Power
Bridge voltage and power ratings (see Appendix B for voltage and
power ratings). If an active splitter is required, be sure to use a
splitter with the correct power rating.

2-8

To connect end devices to the Power Bridge

1. Connect a Category 5, 6, or 6e cable to the end device directly (if
the device is Power over LAN Enabled) or use an external splitter.

2. Connect the opposite end of the same cable to the RJ-45 wall outlet.
Monitor the response of the corresponding Port LEDs. If the Power
Active LED lights up, the Power over LAN hub has identified your
end device as a Power over LAN Enabled device, and the port is
sending po we r.

Commonly Asked Technical Support Questions

Problem/Question Possible Solution/Answer

The Power Bridge is
plugged into the main
AC inlet but does not
power up.

Power Bridge is plugged
in and running, but the
fans are not working.

Power Bridge operates
but the AC/Main LED is
off.

The Power Bridge has
powered up and the
Alarm LED remains lit,
or the Main LED is lit
(or blinks) in red.

The Power Active LED is
lit, but one of the end
devices does not operate.

Verify that the AC power cord is correct,
functioning, and has a solid ground connection.

Verify that the AC inlet is supplying power (test
with a different device) and that the voltage is
from 100 to 264 VAC (50 to 60 Hz).

Reconnect the Power Bridge to the AC inlet and
verify the LED power up sequence.

Verify that none of the fan open i ngs in the case
are blocked.

If fans are not working, you may have an internal
power supply fault.

If both internal fans are working (i.e., air flows
out of the case or can be heard), you may have an
internal circuitry fault.

If fans are not working, you may have an internal
power supply fault.

See the LEDs section in this guide, and
determine if the Power On Self Test (POST)
sequence works as listed. If the LEDs light up in
the correct sequence, the Power Bridge is fully
operational.

If the Alarm LED remains lit following the
POST sequence, the Power Bridge POST
detected an internal fault . Contact your local
dealer.

Verify that the Power Active LED that is lit
corresponds to the end device that is not
working.

The Power Bridge successfully iden tified the end
device as Power over LAN Enabled and is
providing power. Connect a different end device
to the same port—if the end device operates, the
previous end device is faulty.

B-6

Commonly Asked Technical Support Questions (continued)

Problem/Question Possible Solution/Answer

The Power Active and
Power Not Active LEDs
on one port are not lit,
and the corresponding
end device does not
operate.

The Power Bridge did not det ect a connected end
device; therefore, the port is not providing
power. Verify that you are using a standard UTP
Category 5, 6, or 6e cable, including all 8 wires
(4 pairs).

If you are using an external spli tter, you may
have a faulty splitter. Replace your splitter.

Verify that you are not using a crossover t wisted
pair wire.

Verify that the end device i s connected to the
Data & Power Out port (upper RJ-45 connector).

You may have a faulty port or RJ-45 connection.
Reconnect the same end devi ce into a different
port on the same unit.

You may have a faulty connection, a short on the
long cable, or a faulty RJ-45 connection along
the line. Bypass the long twisted pair cable and
bring the end device clos er t o the Power Bridge.
Connect it to one of the ports using a short cable.

You may have a faulty Power Bridge. If possible,
connect the end device to a different Power
Bridge, and then power up again. Verify that the
LEDs light up in proper sequence.

B-7

Commonly Asked Technical Support Questions (continued)

Problem/Question Possible Solution/Answer

The end device operates,
but there is no data link.

Verify that the Power Active LED on the
Power Bridge front panel is lit continuously.

Verify that the Data In and Data & Power Out
ports correspond.

You may have a faulty splitter. Replace your
splitter.

Verify that you are using a standard UTP
Category 5, 6, or 6e cable, including all 8
wires (4 pairs) and is no longer than 100 m
(328 ft) between the switch and t he end
device.

Verify that you are not using any crossover
twisted pair wires.

Verify that the Power Bridge is connected to a
switch/hub with a good RJ-45 patch cord
connection.

You may have a faulty connection, a short on
the long cable, or a faulty RJ-45 connection
along the line. Bypass the long twisted pair
cable and bring the end device closer to the
Power Bridge. Connect it to one of the ports
using a short cable.

You may have a faulty data link in the end
device. Try connecting a different end de vice
to the same port.

You may have a faulty Data & Power Out or
Data In port in the Power Bridge or a faulty
RJ-45 connection. Reconnect the end device to
a different Data & Power Out port and
remember to move the Data In port of the
Switch/Bridge accordingl y.

B-8

Commonly Asked Technical Support Questions (continued)

Problem/Question Possible Solution/Answer

A Power Not Active LED
on one port is lit, and the
end device is not
operating.

One of the ports is
powering an end device
without turning the
Power Act i v e LE D on.

Is it safe to keep the
Power Bridge running
while a Power Not Active
LED is on?

Wait 5 to 10 seconds while the Power Not
Active LED is on and the end device is
connected—if the LED changes to Power
Active, there was a charged capacit or in the end
device, which was discharged after being
plugged in. The end device can then be detected
and activated.

Verify that you are not using any crossover
cable between the Power Bridge Power & Data
Out port and the end device.

The end device may require an external splitter.
If an external splitter is already in use, replace it
with a new splitter. If this is effective, discard
the faulty splitter.

You may have a faulty connection, a short on
the long cable, or a faulty RJ-45 connection
along the line. Bypass the long twisted pair
cable and bring the end device closer to the
Power Bridge. Connect it to one of the ports
using a short cable.

You may have a faulty port or RJ-45
connection. Move the device into a different
output port.

You may have a faulty port or an internal short
in the RJ-45 socket. Unp lug t he device and
verify that the Power Not Active LED turns off.

Reconnect the end device to a different Data &
Power Out port—if the LED turns on, there is a
fault in the previous output port (probably a
faulty LE D) .

Yes, this is a safe condition. Power Not Active
conditions mean that a non-power-ready device
was detected, terminals 4/5 and 7/8 are shorted
together or forced external power feed into the
port. During these conditions, port power is
disconnected; however, a single low power
pulse every 5 seconds continues to sense the
line.
