51 POE Management
Configuration
51.1 Overview
PoE (Power Over Ethernet) is a mechanism that provides 45V~-57V DC to the remote PD
devices (IP Phone, WLAN AP and Network Camera) via twisted pair cables.
The PSE (Power Sourcing Equipment) can transmit both data and current at the same time
via Category 3/5 twisted pair cables (1, 3, 2, 6), with a maximum distance of 100m.
The switch supporting POE can provide the statistics of the power condition of each port and
the entire device, which can be shown through a query command. At the same time, it also
provides overtemperature protection. When the temperature inside the switch exceeds 80
Celsius degrees, the switch will trigger protection by turning off the PoE power supply to all
ports. When the temperature inside the switch is lower than 60 Celsius degrees, the switch
will restore the PoE power supply for all ports.
