Core Product Positioning
The Cisco C9300-PWR-360W (PWR-C1-350WAC-P) is a platinum-rated hot-swappable alternating current power supply developed exclusively for Cisco Catalyst 9300, C9300L and C9300X stackable enterprise switches. It delivers stable DC power for switch control plane, data forwarding ASICs, fan assemblies and interface circuits. This non-PoE power unit is designed for non-powered copper and SFP fiber switch models. It supports single-unit standalone operation or dual redundant load-sharing deployment to improve power reliability for campus, branch office and enterprise access layer networks.
