Cisco PWR-80W-AC enterprise networking (router/Catalyst switch/UCS families) Power Supply

The Cisco PWR-80W-AC is an 80-watt external AC power adapter, its primary application being the Cisco 2504 Wireless LAN Controller (AIR-CT2504), with compatibility extending to the Cisco 800 Series ISR routers that use the same external supply. It accepts a 100-240V AC input and delivers a regulated DC output sized to run the connected appliance from a standard mains socket rather than a rack power feed, which suits both the 2504 WLC (typically deployed at small or branch sites without dedicated rack power) and the desktop/wall-mount 800 Series routers it also serves. Losing this adapter takes the whole appliance down since neither platform has an internal supply of its own, so it is a routine spare for any site running one of these compact, externally-powered devices. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
