MDI/MDI-X Switch
The MDI/MDI-X (Media Dependent Interface/Media Dependent Interface with
Crossover) switch, located on the front panel, is a straight-through or
crossover cable selection switch. It enables the RJ45 port to be connected to a
repeater or DTE device without using a special crossover cable. The default
position of the switch is MDI-X, which means you can connect the RJ45 port to
a workstation or to any other DTE device using a straight-through cable.
