Cisco N01-UAC1 enterprise networking (router/Catalyst switch/UCS families) Server Hardware / Parts

The Cisco N01-UAC1 is a single-phase AC power supply module for the Cisco UCS 5108 Blade Server Chassis, providing hot-swappable input power from a standard AC mains feed to the chassis’s shared power domain. The UCS 5108 typically runs with multiple N01-UAC1 units fitted for N+1 or N+N redundancy, since the chassis’s blade servers, fabric extenders and fan modules all draw from the same shared supply pool rather than each blade having its own power input. It is the single-phase variant of Cisco’s UCS chassis power options, alongside three-phase modules used in larger data-centre power distribution setups. UCS 5108 chassis of this generation remain in service across many established data-centre deployments, and a genuine spare such as this restores power redundancy after a supply failure or replaces a failed unit. Tech-Star (UK-based, shipped worldwide) stocks Cisco UCS components for engineers maintaining these platforms.
