Note With reference to the RJ-45 pinout in Table 6-7, proper common-mode line terminations should be used for the unused Category 5 UTP cable pairs 4/5 and 7/8. Common-mode termination reduces electromagnetic interference (EMI).

Depending on your RJ-45 interface cabling requirements, use the pinouts shown in Figure 6-6and Figure 6-7for Gigabit Ethernet straight-through and crossover twisted-pair cable connections. Use Figure 6-8for Ethernet/Fast Ethernet straight-through and crossover twisted-pair cable connections.
