Straight-Through Wiring
Because the 10/100 Mbps Input port on the power injector uses an MDI pin
configuration, you must use “straight-through” cable for network connections to
hubs or switches that only have MDI-X 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.

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
useeither “straight-through” or “crossover” cable.
