Figure 5-3 Wiring of the straight-through cable

Crossover cable
The wiring for 100 Mbit/s crossover cable is different from that of 1000 Mbit/s crossover
cable.
One RJ45 connector of the 100 Mbit/s crossover cable follows EIA/TIA 568A standard; the
other RJ45 connector follows EIA/TIA 568B standard. Figure 5-4 shows the wiring of the 100
Mbit/s crossover cable.

Figure 5-4 Wiring of 100 Mbit/s crossover cable

The 1000 Mbit/s crossover cable uses all 8 pins of the twisted-pair cable. The crossover is
PIN 1 to PIN 3, PIN 2 to PIN 6, PIN 4 to PIN 7, and PIN 5 to PIN 8, as shown in Figure 5-5.
