the switch is powered through the internal power supply. you can also connect the cisco rps 675 to provide backup power if the switch internal power supply should fail.

    the catalyst 3560 switch and the cisco rps 675 should be connected to the same ac power source.

    internal power supply connector

    the internal power supply is an autoranging unit that supports input voltages between 100 and 240 vac.use the supplied ac power cord to connect the ac power connector to an ac power outlet.

    cisco rps connector

    the switch is powered through the internal power supply. you can also connect the cisco rps 675 redundant power supply (model pwr675-ac-rps-n1=) to provide backup power if the switch internal power supply should fail.

    the catalyst 3560 switch and the cisco rps 675 should be connected to the same ac power source.

    cisco rps 675

    the cisco rps 675 as two output levels: –48 v and 12 v, with a total maximum output power of 675 w.use the supplied rps connector cable to connect the rps to the switch.

    attach only the cisco rps (model pwr675-ac-rps-n1) to the rps receptacle. statement 100c

    the rps is a redundant power system that can support six external network devices and provides power to one failed device at a time. it automatically senses when the internal power supply of a connected device fails and provides power to the failed device, preventing loss of network traffic. for more information on the cisco rps 675, see the cisco rps 675 redundant power system hardware installation guide.
