The UniFi SmartPower Redundant Power System (USP-RPS) is a proprietary redundant power supply system that protects up to six UniFi SmartPower devices from sudden power supply module failures. The USP-RPS continuously monitors all connected devices. In the event of an internal AC/DC power supply failure, the failover occurs automatically, ensuring that your network continues to operate without interruption. With a power output of 950 W, the USP-RPS can protect a variety of high-performance devices, including UniFi PoE switches.
