Catalyst 3750 Switch Hardware Installation Guide

When connecting 10/100 ports to 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. Figure B-5 shows the two
twisted-pair straight-through cable schematics. Figure B-7 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-6 shows the two
twisted-pair crossover cable schematics. Figure B-7 shows the four twisted-pair
crossover cable schematics.
You can use Category 3, 4, or 5 cabling when connecting to
10BASE-T-compatible devices. You must use Category 5 cabling when
connecting to 100BASE-TX-compatible 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.
