It is possible to use either a crossover or a straight Ethernet cable as the Mediatrix units perform automatic MDI/ MDIX detection, meaning that
they adapt to the type of cables connected to them. The Auto MDI/ MDIX feature only works when the unit are configured in auto detect mode,
which is the default mode.
