Cisco Systems, Inc. PWRC451400AC Power Supply

The Cisco PWR-C45-1400AC, also listed as PWRC451400AC, is a 1400-watt AC power supply module for Cisco Catalyst 4500 Series switches. This modular, hot-swappable unit provides up to 1400 W of power to support switching operations, line cards, and PoE-enabled devices when PoE is enabled. It accepts 100–240 VAC input at 50/60 Hz and installs in a dedicated power-supply slot within the Catalyst 4500 chassis, enabling redundancy when multiple supplies are deployed. Designed for enterprise campus and data-center deployments, it helps maintain uptime in critical networks by supporting redundant configurations and integrating its own cooling system. Typical applications include powering IP phones, wireless access points, and surveillance systems in large office networks, educational institutions, government facilities, and other enterprise environments that require continuous network operation.
