Appendix C Cables and Connectors
Connect to 10BASE-T- and 100BASE-TX-Compatible Devices
When connecting the ports to 10BASE-T- and 100BASE-TX-compatible
devices, such as servers, workstations, and routers, you can use a two or four
twisted-pair, straight-through cable 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 wire connected to the
pin on the outside of the left plug should be a different color from the wire
connected to the pin on the inside of the right plug.
The following figures show these schematics:
• Two twisted-pair, straight-through cable
• Four twisted-pair, straight-through cable
Figure 9 - Two Twisted-pair Straight-through Cable Schematic
Figure 10 - Four Twisted-pair Straight-through Cable Schematic
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.
The following figures show these schematics:
• Two twisted-pair, crossover cable schematics
• Four twisted-pair, crossover cable schematics
