Number of Ports That Support PoE 24
Cisco 500 Series switches support the Power over Ethernet Plus (PoE+) standard (IEEE 802.at)
Cisco 500 Series switches are also fully backwards compatible with IEEE 802.11af PoE and previous generation Cisco legacy PoE protocols
The original IEEE 802.3af-2003 PoE standard provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) to each device. Only 12.95 W is assured to be available at the powered device as some power is dissipated in the cable.
The updated IEEE 802.3at-2009 PoE standard also known as PoE+ or PoE plus, provides up to 25.5 W of power.The 2009 standard prohibits a powered device from using all four pairs for power.
