Appendix D Cables and Connectors
Connect to 10BASE-T- and 100BASE-TX-Compatible Devices
The auto-MDIX feature is enabled by default. Follow these cabling guidelines
when the auto-MDIX feature has been disabled.
When connecting the ports to 10BASE-T- and 100BASE-TX-compatible
devices, such as servers and routers, you can use a two or four twisted-pair,
straight-through cable that is wired for 10BASE-T and 100BASE-TX.
To identify a crossover cable, compare the two modular ends of the cable. Hold
the cable ends side-by-side, with the tab at the back. The color of the wire that
is connected to the pin on the outside of the left plug must differ in color from
the wire that is connected to the pin on the inside of the right plug.
Figure 66 and Figure 67 show the cable schematics.

Figure 67 - Four Twisted-pair Straight-through Cable Schematics
When connecting the ports to 10BASE-T- and 100BASE-TX-compatible
devices, such as switches or repeaters, you can use a two or four twisted-pair,
crossover cable.
Use a straight-through cable to connect two ports when only one port is
designated with an X. Use a crossover cable to connect two ports when both
ports are designated with an X or when both ports do not have an X.
