Pre-owned, used and refurbished Cisco WS-C3550-12G

Customers looking for a multilayer Gigabit Ethernet switch that will provide advanced IP routing, deliver enterprise-class intelligent services to the network edge, and can provide a lower TOC for deployments that incorporate Cisco IP phones and/or Cisco Aironet wireless LAN access points, will benefit from the Cisco WS-C3550-12G. With up to 15 Watts of integrated inline power on both 10/100 ports, the WS-C3550-12G 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. Now, you 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 for less when you buy your new surplus or used WS-C3550-12G from us.

The Cisco WS-C3550-12G available from MULTI-LINK (MLCP) isnít the only component in our extensive switch inventory.

Marketing Information

The Cisco Catalyst® 3550 12G is a member of the Catalyst 3550 Series Intelligent Ethernet Switches, 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 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.
