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

The Cisco WS-C5508= is an AC power supply (spare) for the Catalyst 5500 series modular switch chassis, providing mains AC input power to the chassis’s Supervisor Engine and installed line cards. It fits the Catalyst 5500 power-supply bay and can be run singly or alongside a second supply for redundancy depending on chassis load, and is interchangeable in service with other Catalyst 5500-series AC supplies of matching rating. The Catalyst 5500 is the larger-chassis sibling of the Catalyst 5000 in Cisco’s long-established legacy switching platform, and genuine AC power supplies are a routine requirement for maintaining an existing installation, replacing a failed unit, or restoring redundancy. Specifiers should confirm the exact chassis model before ordering, since Catalyst 5000-family power supplies are not universally interchangeable across the wider 5000/5500 range. Tech-Star (UK-based, shipped worldwide) stocks Cisco power supplies to support ongoing network maintenance projects.
