Power over Ethernet (PoE)
Function
The "Power over Ethernet" function supplies connected devices with power via the Ethernet
cable. Devices supplied with power via an Ethernet cable do not require a separate voltage
source.
PoE-compliant devices can be divided into the following groups:
● Power source (PSE - Power Sourcing Equipment)
These inject power onto the Ethernet cable.
● Power consumer (PD - Powered Device)
These are supplied with power via the Ethernet cable.
