CROSSOVER WIRING
Because the 10/100 Mbps port on the power injector uses an MDI pin
configuration, you must use “crossover” cable for network connections to PCs,
servers or other end nodes that only have MDI ports. However, if the device to
which you are connecting supports automatic MDI/MDI-X operation, you can use
either “straight-through” or “crossover” cable.
