Connecting to 1000BASE-T Devices
When connecting the ports to 1000BASE-T devices, such as servers, workstations, and routers, you must
use a four twisted-pair, Category 5, straight-through cable wired for 10BASE-T, 100BASE-TX, and
1000BASE-T.
Figure C-7 shows the straight-through cable schematics.
When connecting the ports to other devices, such as switches or repeaters, you must use a four
twisted-pair, Category 5, crossover cable.
Figure C-8 shows the crossover cable schematics.
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.
