The 10/100 ports are numbered 1X through 4X. The X indicates that the pins on
the port connector are internally crossed. If you are connecting to a device with
ports marked with an X, such as another switch or hub, use a crossover cable. If
you are connecting to devices with ports not marked with an X, such as a PC,
workstation, or server, use a straight-through cable.
For the connector pinouts and schematics, see the section "10/100 Module
Cabling" in Appendix B, "Connectors and Cables."
Always observe the following general rules when connecting
devices: Use a straight-through cable to connect two ports when one
is designated with an X; use a crossover cable to connect two ports
when both are designated with an X.
The 100BaseFX ports use 50/125- or 62.5/125-micron multimode fiber-optic
cabling with duplex SC connectors. When set to run in full-duplex mode,
100BaseFX module ports can connect to compatible devices over distances of up
to 2 kilometers. For connector and schematic information, see Appendix B,
"Connectors and Cables."
GBICs require the following fiber-optic cables with duplex SC connectors.
