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.
