White Paper All You Need To Know About Power over Ethernet (PoE) and the IEEE 802.3af Standard Galit Mendelson Senior Product Manager June 2004

Note that 802.3at exists alongside the 802.3af standard; it does not replace it. 802.3af will still be employed by the majority of Power over Ethernet devices for the foreseeable future. How does POE work? Network cables, such as Cat 5e and Cat 6, comprise eight wires arranged as four twisted pairs.

IEEE 802.3af uses DC powered device detection, however originally Cisco prestandard Power over Ethernet implementation used AC powered device detection. DC detection differs from Cisco's AC detection in that AC detection transmits a low frequency AC signal on the transmit pair and waits for the same signal to be returned on the receive pair.

The original 802.3af PoE standard provides up to 15.4W of power (48 Volts DC at 0.32 Amps) to each device. With PoE+ (802.3at), the maximum output power jumps to 25.5 Watts (48 Volts DC at 0.52 Amps) sustained power and 30 Watts (48Volts DC at 0.63 Amps) peak power. All other 802.3af features are carried over to the new 802.3at standard.
