PoE devices: 1624 BTU/hr) Voltage 100 - 127 / 200 - 240 V ac Current 5.8/2.9 A Idle power1 40.1 W Maximum power rating2 476 W PoE power 382 W Frequency 50/60 Hz NOTE: 1: Idle power is the actual power consumption of the device with no ports connected. 2: Maximum power rating and maximum heat dissipation are the worst-case theoretical maximum numbers provided for planning the infrastructure with fully loaded PoE (if equipped), 100% traffic, all ports plugged in, and all modules populated. PoE power is the total power budget available to all PoE ports.
