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.
Avaya 5600 Family of stackable switches. A stackable switch is a network switch that is fully functional operating standalone but which can also be set up to operate together with one or more other network switches, with this group of switches showing the characteristics of a single switch but having the port capacity of the sum of the combined switches.
