Cisco PWR-C1-1100WAC Industrial Power Supply Module

The Cisco PWR-C1-1100WAC Industrial Power Supply Module delivers up to 1100 W of continuous power for Cisco Catalyst 3850 and 9300 switches, enabling high PoE capacity and redundancy in enterprise access, campus, and data-center deployments. It accepts 115–240 VAC input at 50–60 Hz (approximately 6–12 A) and provides a -56 V DC output, with up to ~94% efficiency and an internal cooling fan with thermal protection. The hot-swappable, plug-in design supports hot replacement to minimize downtime, making it suitable for mission-critical network infrastructures that require reliable power for PoE devices such as IP phones, wireless access points, and security cameras via PoE. Alternate part numbers include PWRC11100WAC and PWR-C1-1100WAC-P, with common replacements such as PWR-C1-715WAC and PWR-C1-350WAC.
