About the PWR-C1-1100WAC
The Cisco PWR-C1-1100WAC is a high capacity 1100 Watt AC power supply module designed for dense PoE+ and 60W UPOE campus access environments. It supplies ample electrical reserves to power high draw access points, pan-tilt-zoom cameras, and compact computing endpoints across all switch ports simultaneously.
Compatibility
Compatible with Cisco Catalyst 9300 Series, Catalyst 9300X Series, and Catalyst 3850 Series switches. It supports hot swap replacement without interrupting network packet forwarding when redundant power supplies are installed and active in the chassis power stack.
How to identify a genuine unit
Enclosed in a full length steel module chassis with a high capacity IEC C16 or C14 connector, heavy duty extraction handle, and diagnostic LEDs. The manufacturing label confirms model number PWR-C1-1100WAC, serial number, and engineering code 341-0531-01.
Buying used
Inspect connector gold plating and ensure the rear exhaust fan spins freely without mechanical obstruction. Test under electrical load in a PoE-equipped switch chassis to confirm stable voltage rail outputs and proper thermal management sensor reporting across all ports.
