Connecting to 10BASE-T- and 100BASE-TX-Compatible Devices
When connecting the ports to 10BASE-T- and 100BASE-TX-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 10BASE-T- and 100BASE-TX-compatible 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-10 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.
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 B-9 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 B-10 shows the
crossover cable schematics.
Note
Be sure to use a four twisted-pair, Category 5 cable when connecting to a
1000BASE-T-compatible device.
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 .
