The UniFi SmartPower Redundant Power System, model USP-RPS, is a proprietary redundant power system designed to protect up to six UniFi SmartPower supported devices from sudden power supply module failure. The USP-RPS continually monitors all attached devices. In the event of an internal AC/DC power supply failure, failover is automatic so your network continues to operate with no interruption in service. With a 950W DC power budget, the USP-RPS can protect a variety of high-power devices, including UniFi PoE switches. An integrated 1.3" color touchscreen LCM displays system information for convenient monitoring.
