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 279 BTU/hr (295 kJ/hr)
Voltage 100-127/200-240 VAC
Current 1.7/0.9 A
Idle power 49 W
Maximum power rating 82 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.
