Power Over Ethernet (PoE+) Operation
Introduction to PoE+
Introduction to PoE+
PoE technology allows IP telephones, wireless LAN access points, and other
appliances to receive power and transfer data over ethernet LAN cabling.
Using an available power supply of 382 watts, PoE can deliver up to 15.4
watts of power to 24 PoE ports over category 3 cabling. PoE+ can deliver up
to 30 watts of power to 12 PoE+ ports over category 5 cabling. PoE+ also
supports delivery of PoE power concurrently with 10/100/1000 Gbps of data
transmission.
Additionally, PoE+ provides more power-management capability, allowing the
switch to have more power available for more PDs. Power can be allocated
exactly and automatically according to what the PD actually requires at a given
time.
