Cisco PWR-C2-250WAC enterprise networking (router/Catalyst switch/UCS families) Power Supply

The Cisco PWR-C2-250WAC is a 250W AC power supply built to the “Config 2” power-bay layout used on smaller Catalyst switches, distinct from the larger Config 1 bay fitted to higher-capacity chassis in the same product families. It is the entry-level wattage point in the Config 2 supply range, suited to switches with a modest PoE budget or no PoE requirement at all, and a failed or missing unit on a single-supply switch takes the whole switch offline. Confirm your switch model uses the Config 2 PSU bay and that 250W meets its total power and PoE budget requirement before ordering, since higher-wattage Config 2 supplies (such as the 640W variant) are not interchangeable substitutes if more power is actually needed. Tech-Star (UK-based, shipped worldwide) supplies Cisco Catalyst power supplies to keep switch capacity correctly matched.
