Cisco 1100W AC 80+ Platinum Configuration 1 Power Supply

The Cisco PWR-C1-1100WAC-P= is a power supply that delivers 1100 watts of AC power to Cisco Catalyst 9300 Series switches, keeping them stable and ready for the traffic your network demands. It operates across an input range of 115 to 240 volts alternating current, so it fits neatly into electrical systems found in offices, campuses, and data centers worldwide.

An 80 PLUS Platinum efficiency rating allows the unit to convert most of the incoming electricity into usable power for the switch instead of wasting it as heat. The result is lower utility bills, reduced cooling requirements, and a smaller environmental footprint, advantages that matter in energy conscious facilities and dense wiring closets.

The module installs quickly and supports hot-plug operation. You can slide it in or out while the switch is live, which helps avoid service interruptions during maintenance or capacity upgrades. Network administrators who manage high availability environments, such as enterprise core layers, manufacturing floors, or busy classroom networks, will appreciate the ability to swap power supplies without scheduling downtime.

Keeping one or more of these supplies on hand also simplifies disaster recovery and future expansion. By choosing a model meant specifically for the Catalyst 9300 Series, you ensure full compatibility and preserve the reliable performance that is expected from Cisco infrastructure.
