When connecting the 10/100 ports to compatible workstations, servers, routers,
and Cisco IP Phones, you must use a straight-through cable wired for 10BASE-T
and 100BASE-TX. (Figure B-5
When connecting to other switches or repeaters, you must use a crossover cable.
(Figure B-4 shows the crossover cable schematics.)
Use a straight-through cable to connect two ports when one of the ports is
designated with an X. Use a crossover cable to connect two ports when both
connectors and cables are designated with an X or when both ports do not have an
X.
100BASE-FX ports use duplex SC connectors, as shown in
ports use 10/125- or 62.5/125-micron multimode fiber-optic cabling.
