The regular RJ-45 ports support the standard for hubs-to-users twisted pair
wiring: pin 1= receive+, 2 = receive-, 3 = transmit+, 6 = transmit-, other pins
not used. The RJ-45 port with the MDI-X switch is normally the same, but
when switched it supports the standard for up-links using twisted pair wiring,
i.e., the transmit and the receive pairs are exchanged: pin 1 = transmit+, 2 =
transmit-, 3 = receive+, 6 = receive- , other pins not used.
