This desktop switch is designed for small offices and larger workgroups. All ports auto-sense the network speed of the computers and hubs to run at either 10Mbps or 100Mbps. The ports also auto-negotiate between full and half duplex and support flow control. Expansion is easy through a MDI uplink port. You cascade several switches together through this port to get more ports. IEEE 802.3x Flow Control allows your servers to directly connect to this switch for fast, reliable data transfer.
