The Cisco Redundant Power System 300 (RPS 300) is designed to increase availability in a converged data, voice, and video network. The system delivers superior internal power supply redundancy and resiliency at an affordable price.The Cisco RPS 300 supports internal power supply redundancy for up to six Cisco networking devices and features an innovative power architecture that provides customers with an immediate failover capability. The Cisco RPS 300 incorporates a quick failover feature, ensuring customers that the connected device will not reboot in the event of an internal power supply failure. For example, if an internal power supply fails on one of the six connected devices, the Cisco RPS 300 automatically senses the failure and delivers uninterrupted power to that device. When a failure is detected, the Cisco RPS 300 sends an alert that the other connected devices will not be supported until the failed device is restored or replaced. This alert can be monitored through CiscoWorks 2000 and the Cisco Cluster Management Suite (CMS) Web-based network management. To achieve one-to-one redundancy, each device must be connected to a separate Cisco RPS 300. The Cisco RPS 300 can be combined with the Catalyst 3524-PWR Series XL desktop switch, featuring inline power and an uninterruptible power supply (UPS) system, to establish all of the elements of the Cisco Centralized Power Provisioning System. This combination provides a resilient, highly available converged network, offering internal redundant power to the switch; power to the IP phone via the switch's inline power feature (rather than wall power); and back-up in the event of a power outage.
