The Cisco Redundant Power System 2300 (RPS 2300) increases availability for converged data,voice,and video networks. The system delivers power supply redundancy and resiliency for a variety of power requirements,including Power over Ethernet (PoE). It helps ensure uninterrupted operation and protection against device power supply failures by providing seamless failover for Cisco switches like the Cisco Catalyst 3750-E Series Switches and routers like the Integrated Services Routers. The Cisco RPS 2300 supplies redundant power for up to two of six connected 48-port PoE devices in a convenient,1-rack-unit form factor. When attached to Cisco Catalyst 3750-E or 3560-E Series Switches,the Cisco RPS 2300 offers additional intelligent management capabilities.
