Power over Ethernet (PoE)
With PoE, the power for networked devices is carried via Ethernet. Here, there are two methods
of supplying power:
• Alternative A
Here, the voltage is transferred on the data wires 1, 2, 3 and 6 of the Ethernet cable
Requirements for the Ethernet cable:
– For 10Base-T/100Base-TX, a 4-wire cable is adequate for data transmission and power
supply.
– With 1000BASE-T, an 8-wire cable is necessary for data transmission.
• Alternative B
Power is transferred on the free wires 4, 5, 7 and 8 of the Ethernet cable.
Requirements for the Ethernet cable: For 10Base-T/100Base-TX/1000BASE-T, an 8-wire cable
is needed.
PoE-compliant devices can be divided into the following groups:
• PSE - power sourcing equipment
These inject power onto the Ethernet cable.
• PD - powered devices
These are supplied with power via Ethernet.
