Four Twisted-Pair Straight-Through Cable Pinouts for 10/100/1000 and 1000BASET GBIC Module Ports

Chapter 3 Installing a Cisco 7200 VXR Router

Connecting I/O Controller, NPE-G1, or NPE-G2 Cables

Note With reference to the RJ-45 pinout in Table 3-1, proper common-mode line terminations should be used for the unused Category 5 UTP cable pairs 4/5 and 7/8. Common-mode line termination reduces electromagnetic interference (EMI).

Depending on your RJ-45 interface cabling requirements, use the pinouts shown in Figure 3-21and Figure 3-22for Gigabit Ethernet straight-through and crossover twisted-pair cable connections. Use Figure 3-23for Ethernet/Fast Ethernet straight-through and crossover twisted-pair cable connections.
