The Cisco 550X series Stackable Managed Switches are the next-generation stackable Managed Ethernet switches that provide the advanced capabilities and superior performance you need to support a more demanding network environment at an affordable price. These switches incorporate fan and power hardware redundancy, increasing overall network availability. The Cisco 550XG models provide 10 Gigabit Ethernet with both copper and fiber connection options, providing a solid foundation for your current business applications, as well as those you are planning for the future. At the same time, these switches are easy to deploy and manage, without a large IT staff. Cisco 550X series switches are designed to protect your technology investment as your business grows. Unlike switches that claim to be stackable but have elements that are administered and troubleshot separately, the Cisco 550X series provides true stacking capability, allowing you to configure, manage, and troubleshoot multiple physical switches as a single device and more easily expand your network. A true stack delivers a unified data and control plane, in addition to a management plane, providing flexibility, scalability, and ease of use because the stack of units operate as a single entity constituting all the ports of the stack members.
