Uplink or MDI Function
A network of switches connected (or cascaded) together via uplink ports is termed a “collapsed backbone.” The
uplink function transforms the adjacent or indicated port into an uplink port with a push of the button or by sliding
the switch. This allows connection to another switch or hub without preparing crossover cable. However, this is
unnecessary when either connecting directly to the uplink port of another switch or hub or when connecting fiber
ports between switches or hubs.
