1000BASE
straight-through
cable
For 1000BASE network connections, all four pairs are used and the cable is
wired in a straight-through configuration. You can use this cable with the
software test facility to test 1000BASE network ports. The following table lists
pin assignments for a 10/100/1000BASE-T RJ-45 four pair straight-through
cable.
1000BASE
crossover cable
For 1000BASE test cables, all four pairs are used and the cable is wired in either
a crossover or straight-through configuration. The following table lists pin
assignments for a 10/100/1000BASE-T RJ-45 four pair crossover cable.
Cable Guidelines
The following table lists port, connector, and cable combinations for switch
models and expansion modules.
