Appendix A Twisted -pair and Pin Distribution
For the 10Base-T/100Base-TX, the twisted-pair should present two pair of wires. Each
pair is differentiated by different colors. For instance, the one is green and the other is
the green and white interleaved. There should be the RJ-45 connector at both sides of
cables.
Warning:
Don’t plug the telephone jacket into any one RJ-45 port. Only the twisted-pair which
complies with the FCC standard is used. Furthermore, both sides present the RJ-45
connectors.
Fig.A-1 illustrates how to number the RJ-45 connector, please confirm the consistence
of the direction when it is inserted.

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
