    Cisco SG550XG-48T 48-Port 10GBase-T Stackable Managed Switch

    Cisco SG550XG-48T 48-Port 10GBase-T Stackable Managed Switch

    The Cisco 550XG models provide 16, 24, or 48 ports of 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. With 10G copper ports on those switches, you can easily and cost-effectively enable 10G connections to servers and network storage devices with standard RJ45 Ethernet cable. You can also connect the 10G SFP+ fiber ports to 10G uplinks of your access switches, building a high-performance aggregation or core to speed up the overall operation of your network.
