Connector Specifications
Connecting to 1000BASE-T Devices
When you connect 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-5 shows the straight-through cable schematics.
When you connect the ports to other devices, such as switches or repeaters, you must use a four
twisted-pair, Category 5, crossover cable. Figure B-6 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.
