The ISW-Series switches are powered by up to two external DC power supplies. The DC power input can be provided either by the DC power line available at the installation site or by using one of the supported AC input to DC output power supplies. Both power supplies must have the same power rating, such as 240W, for long term use. You can remove one power supply without interrupting the switch's operation. The ISW-Series switch can support an unmatched pair of power supplies for a short time while you are upgrading or downgrading.
Refer to ISW Series Technical Specifications for the input ratings of the switches and the output ratings of the power supplies.
Power supplies are ordered separately.
