When connecting 10/100 ports to other 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. Figure B-6 shows the two twisted-pair,
straight-through cable schematics. Figure B-8 shows the four twisted-pair,
straight-through cable schematics.
When connecting the ports to other devices, such as switches or repeaters, you can
use a two or four twisted-pair, crossover cable. Figure B-7 shows the two
twisted-pair, crossover cable schematics. Figure B-9 shows the four twisted-pair,
crossover cable schematics.
You can use Category 3, 4, or 5 cabling when connecting to 10BASE-T devices.
You must use Category 5 cabling when connecting to 100BASE-TX devices.
Note Use a straight-through cable to connect two ports only when 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.
