Electrical characteristics

Description The switch automatically adjusts to any voltage between 100-127 and 200-240 volts and either 50 or 60 Hz
Maximum heat dissipation 667 BTU/hr (704 kJ/hr), max. using PoE+
Voltage 100-127/200-240 VAC
Current 6.4/3.2 A
Idle power 89 W
Maximum power rating 556 W
PoE power 382 W
Frequency 50/60 Hz
Notes Idle power is the actual power consumption of the device with no ports connected.
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 power supplied by the internal power supply. It is dependent on the type and quantity of power supplies and may be supplemented with the use of an external power supply (EPS).
