Pin distribution of 10Base-T/100Base-TX
RJ-45 connection adopts the Unshielded Twisted Paired (UTP) or the
Shielded Twisted Pair (STP): the 10Mbps connection adopts the 100ohm
of Cat3, Cat4 and Cat5, while the 100Mbps connection adopts the 100ohm
of Cat5. Furthermore, keep in mind that the connection length of any
twisted-pair should no be more than 100m.
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.
