Cisco NC55-PWR-3KW-AC= network switch component Power supply

The Cisco NCS 5500 Series supports hot-swappable, front-panel-accessible power supplies. N+1 and N+N (grid) redundancy modes are supported for a fully loaded Cisco NCS 5508, and N+1 and N+M redundancy modes are supported for a fully loaded Cisco NCS 5516. The 3000W AC and DC power supplies are 80 Plus Platinum rated, providing more than 92 percent efficiency across typical workloads. The additional unused power-supply slots are not needed with existing line cards, but they offer headroom to support higher-bandwidth line cards in the future. - 3000W AC power supply, single 20A input, 220V - N+1 or N+N grid redundancy supported for Cisco NCS 5508 - N+1 or N+M redundancy supported for Cisco NCS 5516 - Hot swappable - Front-panel-accessible - 50 to 60 Hz frequency - 92% or greater efficiency (20 to 100% load) - RoHS compliant
