Standards development
The original IEEE 802.3af-2003[1] PoE standard provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA[2][3]) on each port.[4] Only 12.95 W is assured to be available at the powered device as some power dissipates in the cable.[5] The updated IEEE 802.3at-2009[6] PoE standard also known as PoE+ or PoE plus, provides up to 25.5 W of power for Type 2 devices.[7] The 2009 standard prohibits a powered device from using all four pairs for power.[8] Both of these standards have since been incorporated into the IEEE 802.3-2012 publication.[9
