Overview
A PoE device is Power Sourcing Equipment (PSE) that delivers electrical power to a
connected Pod Devices (PD) over existing copper cables without interfering with the network
traffic, updating the physical network or modifying the network infrastructure.
Features
PoE provides the following features:
• Eliminates the need to run 110/220 V AC power to all devices on a wired LAN.
• Removes the necessity for placing all network devices next to power sources.
• Eliminates the need to deploy double cabling systems in an enterprise significantly
decreasing installation costs.
Power over Ethernet can be used in any enterprise network that deploys relatively low-pod
devices connected to the Ethernet LAN, such as:
• IP phones
• Wireless access points
• IP gateways
• Audio and video remote monitoring devices
