Cisco WS-C3550-12G enterprise networking (router/Catalyst switch/UCS families) Datacentre Switch

The Cisco WS-C3550-12G is a Catalyst 3550-12G fixed-configuration switch, providing 10 Gigabit Ethernet GBIC-based ports plus two additional 10/100/1000BaseT copper Gigabit ports. The 3550 Series was Cisco’s multilayer (Layer 2/Layer 3) fixed-configuration switch family, and the 12G variant was the high-density all-Gigabit member of the range, aimed at aggregation or small-core roles where every port needs Gigabit rather than Fast Ethernet capacity. The GBIC slots allow a mix of fibre and copper Gigabit interfaces to be fitted as needed, which made the 3550-12G a flexible choice for fibre-fed wiring closets or small server-farm aggregation points. It remains a working spare for 3550-series deployments still in service, whether replacing a failed unit or adding Gigabit aggregation capacity to an existing installation. Confirm your required IOS feature set (EI vs SI-equivalent) before ordering. This is a refurbished unit, shipped worldwide from Tech-Star’s UK stock.
