OVERVIEW
PoE PD Switches are perfect for your network’s edge.
Unlike most PoE switches which are PSEs that provide power
to PoE devices, these switches are PDs and receive their power
from a PSE. Because their power is delivered over the UTP
Ethernet cable, they don’t need a separate power outlet,
saving you money on installation costs. These switches are an
easy way to extend the range of your Ethernet network and
increase port density.
Powered by Ethernet
PoE PD Switches receive their power from any PoE PSE
device across CAT5 or higher UTP cable. Because they’re
powered by the same cable that provides their Ethernet
connection, installation is simplified and you don’t need to
worry about having power outlets at remote locations.
A wide range of port options
These nimble switches are available with copper ports only
or with copper ports plus a fiber uplink. There is even a model
with an SFP port which enables you to use SFPs for greater
flexibility on the fiber link. One copper port on each switch
supports PoE.
Use models with fiber ports to add long-distance fiber
links—up to 100 km—to your network. Single-strand fiber
models enable you to send and receive over a single fiber
strand, so you get more use from your fiber infrastructure.
One port on each switch is a high-priority VoIP port which
ensures that voice packets get through first.
A full-featured switch
PoE PD Switches provide the features you’re looking for.
All copper ports are dual-speed, autosensing 10-/100-Mbps
ports. MDI/MDI-X means you never need to worry about
having a crossover cable.
Broadcast storm protection (message rate filtering)
prevents network downtime by shutting down ports if
broadcast or multicast traffic exceeds its threshold.
DiffServ on all ports provides quality of service (QoS)
prioritization so crucial network traffic gets through first.
Link Loss on all fiber ports notifies you if the fiber link fails.

The seemingly universal network connection, twisted-pair
Ethernet cable, has another role to play, providing electrical
power to low-wattage electrical devices. Power over Ethernet
(PoE) was ratified by the Institute of Electrical and Electronic
Engineers (IEEE) in June 2000 as the 802.3af-2003 standard.
It defines the specifications for low-level power delivery—
roughly 13 watts at 48 VDC—over twisted-pair Ethernet cable
to PoE-enabled devices such as IP telephones, wireless access
points, Web cameras, and audio speakers.
The way it works is simple. Ethernet cable that meets CAT5
(or better) standards consists of four twisted pairs of cable,
and PoE sends power over these pairs to PoE-enabled devices.
In one method, two wire pairs are used to transmit data, and
the remaining two pairs are used for power. In the other
method, power and data are sent over the same pair.
When the same pair is used for both power and data, the
power and data transmissions don’t interfere with each other .
Because electricity and data function at opposite ends of the
frequency spectrum, they can travel over the same cable.
Electricity has a low frequency of 60 Hz or less, and data
transmissions have frequencies that can range from 10 million
to 100 million Hz.
There are two types of devices involved in PoE configurations: Power Sourcing Equipment (PSE) and Powered Devices
(PD).
PSEs, which include end-span and mid-span devices,
provide power to PDs over the Ethernet cable. An end-span
device is often a PoE-enabled network switch that’s designed
to supply power directly to the cable from each port. The
setup would look something like this:
A mid-span device is inserted between a non-PoE device
and the network, and it supplies power from that juncture.
Here is a rough schematic of that setup:
Power injectors, a third type of PSE, supply power to a
specific point on the network while the other network
segments remain without power.
PDs are pieces of equipment like switches, surveillance
cameras, sensors, wireless access points, and any other
devices that operate on PoE.

TYPICAL APPLICA TIONS
• Use one set of twisted-pair wires for both data and power.
• Save money by eliminating the need to run electrical
wiring.
• Quickly set up a temporary workgroup.
• If your LAN is protected from power failure by a UPS, the
PoE PD Switches connected to your LAN are also protected
from power failure.
• Use the switch increase the range of your copper network
by enabling you to add up to another 100 meters of UTP
cabling.
