A PoE switch is PSE (Power Sourcing Equipment) that delivers electrical power to
connected PD (Powered Devices) over existing copper cables without interfering
with the network traffic, updating the physical network or modifying the network
infrastructure.
PoE 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.
