Electrical characteristics

Frequency

50/60 Hz

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

Maximum power rating

556 W

Idle power

89 W

PoE power

382 W

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).

Safety

EN 60950/IEC 60950CAN/CSA 22.2 No. 60950EN 60825UL 60950

Notes

When using mini-GBICs with this product, mini-GBICs with revision "B" or later (product number ends with the letter "B" or later, e.g., J4858B, J4859C) are required.
