Cisco PWR-2921-51-POE: AC power supply with internal PoE for the Cisco 2921 Integrated Services Router.

The Cisco PWR-2921-51-POE is an AC power supply with internal Power over Ethernet support, built for the Cisco 2921 Integrated Services Router (ISR G2). The 2921 is a modular branch-office router combining routing, security and voice services in one chassis, and this supply is sized to run the router itself plus PoE to any onboard or module-based Ethernet switch ports feeding IP phones or access points directly from the router, without needing a separate PoE injector. It is specific to the 2921 platform’s power budget and connector footprint rather than a generic ISR G2 supply, so it should not be assumed interchangeable with the supplies used on the smaller 2901 or larger 2951 in the same family. ISR G2 routers of this generation remain widely deployed at branch and small-office sites, and a working power supply is a hard dependency for the whole router, making a spare a sensible stock item. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
