Cisco WS-C4006 enterprise networking (router/Catalyst switch/UCS families) Datacentre Switch

The Cisco WS-C4006 is a 6-slot chassis from the Catalyst 4000 Series, an earlier-generation modular switch platform that predates the still-current Catalyst 4500 range. This listing is the bare chassis only, supplied without a power supply or fan tray, both of which are separate field-replaceable items on the Catalyst 4000 architecture; a working switch needs a compatible supervisor engine, at least one power supply and the fan tray fitted before it will run. The Catalyst 4000/4006 was a common campus and wiring-closet chassis through the late 1990s and 2000s, accepting a range of Ethernet line cards alongside its supervisor slot, and has long been superseded by the Catalyst 4500-X and 9000 Series ranges. A bare chassis of this kind is typically bought to rebuild a system from parts, or to add capacity to an existing Catalyst 4000 deployment still running in a legacy site. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
