The Cisco Catalyst 3550 Series Intelligent Ethernet Switches is a line of enterprise-class, stackable, multilayer switches that provide high availability, security and quality of service (QoS) 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 small networks. Customers can deploy network-wide intelligent services, such as advanced QoS, rate-limiting, Cisco security access control lists, multicast management, and high-performance IP routing – while maintaining the simplicity of traditional local area network (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 networks and intelligent network services.

The Catalyst 3550-24 PWR switch can provide a lower total cost of ownership for deployments that incorporate Cisco IP phones and/or Cisco Aironet wireless LAN access points. With up to 15 Watts of integrated inline power on every 10/100 port, the switch provides maximum device support and eases new technology deployments by eliminating the need for wall power to each IP phone or wireless LAN access point. Additionally, delivering power via the Catalyst 3550-24 PWR switch eliminates the cost for additional electrical cabling that would otherwise be necessary in wireless LAN and IP phone deployments. Maximum power availability for a converged voice and data network is attainable when a Catalyst 3550 Switch is combined with the Cisco Redundant Power System 675 (RPS 675) for seamless protection against internal power supply failures and an uninterruptable power supply (UPS) system to safeguard against power outages.
