Cisco WS-C5508 enterprise networking (router/Catalyst switch/UCS families) Datacentre Switch

The Cisco WS-C5508 is a hot-swappable 1100W AC power supply for the Catalyst 5500 series modular switch chassis, accepting a 110/220V AC input and plugging directly into one of the chassis’s power bays. The Catalyst 5500 is a 13-slot enterprise switching platform that scales beyond 50Gbps of backplane capacity, and a chassis running a full complement of Supervisor and line-card modules typically needs this level of supply headroom, with a second WS-C5508 fitted for N+1 redundancy on larger builds. It is the same supply family documented as the WS-C5508/2 secondary unit. Catalyst 5500 chassis of this generation remain in service in a number of established enterprise networks, and a genuine spare such as this restores full power budget after a supply failure or adds redundancy to an existing chassis. Tech-Star (UK-based, shipped worldwide) stocks Cisco power supplies for engineers maintaining these platforms.
