The X refers to the fact that transmit wires on an MDI device must be connected to receive wires on an MDI-X device. Straight-through cables connect pins 1 and 2 (transmit) on an MDI device to pins 1 and 2 (receive) on an MDI-X device. Similarly, pins 3 and 6 are receive pins on an MDI device and transmit pins on an MDI-X device.
