Protect access-layer availability with an external redundant power supply designed for PoE-dependent networks. The Extreme Networks RPS-950W delivers 950 W of total output and supports up to 740 W of PoE load, giving critical edge devices a second power path when the primary supply is unavailable. This model is built for environments where downtime is expensive: voice networks, surveillance systems, and wireless infrastructure that must stay online during a PSU failure. By adding redundancy at the switch level, it helps preserve service continuity without redesigning the power architecture. For infrastructure teams, the value is straightforward. You get a purpose-built redundancy option sized for access switches that carry real PoE demand, not a generic backup supply. That makes it a stronger fit than lower-capacity alternatives when the switch is powering multiple endpoints and the cost of interruption is measured in lost connectivity, not just lost watts.
