External Power Supply Micro Repeaters - Allied Telesis AT-MR111T User Manual

This switch allows for use with a UTP cable wired as straight-through (MDI
interface) or wired with the TX pair crossed with the RX pair (MDI-X interface).
That is, when connecting the micro repeater to a 10Base-T repeater or Hub, a
straight-through cable could be used and the switch would be in the
non-crossover position (MDI). If the UTP port is connected to a 10Base-T
transceiver and a straight-through cable is used, then the switch should be in
the crossover (MDI-X) position.
