Cisco 3504 Controller Power Supply PWR-115W-AC=

Restore power to a Cisco 3504 wireless controller with the PWR-115W-AC= replacement supply. Built for the 3504 platform, this 115 W AC unit is the right fit when you need to return a controller to service without introducing compatibility risk. For infrastructure teams, that matters: a matched power supply shortens recovery time, reduces troubleshooting, and keeps wireless operations moving. This is the kind of part you keep on hand for fast swap-in replacement during maintenance windows or unplanned failures. Instead of adapting a generic power source, you get a supply intended for the controller’s electrical and mechanical requirements. That helps preserve uptime, simplifies spares planning, and supports a cleaner service process for environments where wireless access is tied to business continuity. For organizations standardizing on Cisco hardware, OEM replacement parts also help maintain consistency across the fleet. The result is a more predictable support path and less time spent validating compatibility. When the controller is critical to access, guest connectivity, or branch operations, a verified replacement power supply is the practical choice.
