Cisco PWR-C1-1100WAC-P – 1100W AC 80+ Platinum Power Supply for Catalyst Switches

Cisco PWR-C1-1100WAC-P is a 1100W AC Platinum-rated hot-swappable Power Supply designed for Catalyst 3850 and 9300 Switches, supporting efficient Power delivery and redundant configurations. Matching on sight is unreliable here. The part number is what determines whether it will work in a given chassis.

Redundancy only works if they match. A pair of supplies has to be the same model and the same airflow direction, or the chassis will either refuse the second unit or run it in a way that defeats the point. Check the chassis generation first, since supplies with identical connectors are frequently not interchangeable, then the input type and the output rating against the full load.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. Quote the equipment it is for when you ask and we will verify the fit first. We come back by the next working day.

The Cisco PWR-C1-1100WAC-P is a 1100-watt AC power supply module designed for enterprise-class Cisco switches, particularly the Cisco Catalyst 3850 and Catalyst 9300 Series. This high-efficiency power supply delivers reliable power to support demanding switching environments and PoE deployments.

The module features an 80 PLUS Platinum efficiency rating, reducing energy loss and minimizing heat generation while maintaining consistent power delivery. It supports hot-swappable installation, allowing administrators to replace or add the power supply without powering down the switch, which helps maintain continuous network operation.

With an input range of 115–240 V AC (50–60 Hz) and a maximum 1100 W output capacity, the unit provides strong power delivery for switches running multiple PoE+ devices such as wireless access points, IP phones, and surveillance cameras. The module also supports redundant power configurations, enabling two power supplies to operate in parallel for high-availability network environments.

This power supply is widely deployed in enterprise campus networks, branch infrastructures, and data-center edge environments where reliability, efficiency, and uptime are critical.

Key Features:

• 1100 W AC output power for Cisco enterprise switches

• 80 PLUS Platinum efficiency for reduced energy consumption

• Hot-swappable power supply module for minimal downtime

• Supports redundant power configurations for high availability

• Compatible with Cisco Catalyst 3850 and Catalyst 9300 Series switches
