The RJ-45 port supports the automatic MDI/MDI-X operation, and can use the
direct connection wire to connect the PC or server, or connect other switches or
hubs. In the direct connection wire, pin 1, 2, 3 and 6 are at the same end of the
cable and are connected to the pin 1, 2, 3 and 6 at the other end of the connection
cable. If it is necessary to connect to the switches or hubs with MDI-X port, it
needs to use the crossover wire. For the concrete condition on the 10Base-
T/100Base-TX pin assignment, refer to table A-1.
