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 3-21 and Figure 3-22 for Gigabit Ethernet straight-through and crossover twisted-pair cable connections. Use Figure 3-23 for Ethernet/Fast Ethernet straight-through and crossover twisted-pair cable connections.

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 3-21
and
Figure 3-22
for Gigabit Ethernet straight-through and crossover twisted-pair cable connections. Use
Figure 3-23
for Ethernet/Fast Ethernet straight-through and crossover twisted-pair cable connections.
