10/100BASE-TX Pin Assignments
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45
connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or
100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the
length of any twisted-pair connection does not exceed 100 meters (328 feet).
The RJ-45 Input port on the power injector is wired with MDI pinouts. This means
that you must use crossover cables for connections to PCs or servers, and
straight-through cable for connections to switches or hubs. However, when
connecting to devices that support automatic MDI/MDI-X pinout configuration, you
can use either straight-through or crossover cable.
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.
