Introduction

Power- -over Ethernet (PoE) eliminates the need to run DC power to other devices on a single wired

LAN. Using Power- -Over Ethernet, installers only need to run a single CAT 5cable carries that both

data and power to each device. This allows flexibilliy greater in the location of the network

devices. And in many cases significantly decreases the installation costs.

There are two system components in the PSE (Power Sourcing Equipment) and the PD PoE –

(Powered Device). The IEEE 802.3af/at specification defines PSE as a device that inserts power

onto an Ethernet cable. The PSE may be located at the switch (Endspan configuration). Or it may

be a separate device (Poe Injector) located between the switch and the PD (Midspan

configuration). The PD is the natural termination of this link, receiving the power and the data

And it could be an IP camera or an IP phone or a WLAN Access Point that require power.

The current is transmitted over 2 of the 4 twisted pairs of wires in a Category 5, 6, 7 cable.-

Power- -over Ethernet follows the IEEE 802.3af/at specification and is completely compatible

with existing Ethernet switches and networked devices. Because the Power Sourcing Equipment

(PSE) tests whether a networked device is PoE-capable, power is never transmitted unless a

Powered Device is at the other end of the cable. It also continues to monitor the channel. If the

Powered Device does not draw a minimum current, because it has been unplugged or physically

turned off, the PSE shuts down the power to that port.

Optionally, the standard permits Powered Devices to signal th the PSEs exactly how much power

they need.

The PoE switch is a multi-port fast Ethernet switch that can be used to build high-performance

switched workgroup networks. This switch is a store- -and forward device that offers low latency for

high-speed networking. It also features a “store- -and forward” switching scheme that allows the

switch to auto-learn and store source addresses in a 8K-entry MAC address table. The switch is

targeted at workgroup, department or backbone computing environments.
