Cisco Catalyst 3550-24 SMI - Switch - 24 ports - EN, Fast EN - 10Base-T, 100Base-TX + 2 x GBIC (empty) - 1U

The Cisco Catalyst 3550 Series Intelligent Ethernet Switches is a new line of enterprise-class, stackable, multilayer switches that provide high availability, scalability, security and control to enhance the operation of the network. With a range of Fast Ethernet and Gigabit Ethernet configurations, the Catalyst 3550 Series can serve as both a powerful access layer switch for medium enterprise wiring closets and as a backbone switch for mid-sized networks. For the first time, customers can deploy network-wide intelligent services, such as advanced quality of service (QoS), rate-limiting, Cisco security access control lists, multicast management, and high-performance IP routing - while maintaining the simplicity of traditional LAN switching. Embedded in the Catalyst 3550 Series is the Cisco Cluster Management Suite (CMS) Software, which allows users to simultaneously configure and troubleshoot multiple Catalyst desktop switches using a standard Web browser. Cisco CMS Software provides new configuration wizards that greatly simplify the implementation of converged applications and network-wide services. The Catalyst 3550-24-DC switch is a workgroup Ethernet switch equipped with an on-board direct-current (DC) power converter. The DC-power converter has dual primary feeds (A and B) that are diode OR'd into a single power block.
