The Cisco Catalyst 1900 is a 19" rack mountable, managed (configurable) 10baseT ethernet switch with 2 100baseTX Uplink Ports
This is an excellent switch for learning the Cisco IOS. It's also perfect for traffic aggregation on a home network. for example, if this switch is used in conjunction with a cable/DSL router it instantly gives 24 ports on the LAN. Or configure VLANS to separate/isolate traffic.
