Connecting I/O Controller, NPE-G1, or NPE-G2 Cables Chapter 3 Installing a Cisco 7200 VXR Router Connecting to the I/O Controller Ethernet and Fast Ethernet Ports The I/O controller Ethernet and Fast Ethernet ports use two types of ports, RJ-45 ports or MII ports, depending on which I/O controller model you have. The following sections explain the Ethernet and Fast Ethernet connection equipment. Ethernet and Fast Ethernet RJ-45 Connections The I/O controller has RJ-45 ports for Ethernet, Fast Ethernet, or autosensing Ethernet and Fast Ethernet connections, depending on your model. The RJ-45 ports support IEEE 802.3 (Ethernet) and IEEE 802.3u (Fast Ethernet) interfaces compliant with 10BASET and 100BASETX specifications. The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP) cables with RJ-45 connectors. Cisco Systems does not supply Category 5 UTP cables; these cables are available commercially. Figure 3-20 shows the RJ-45 port and connector. Table 3-11 lists the pinouts and signals for the RJ-45 connector. Figure 3-20 RJ-45 Port and Connector 12345678 84529 1 1 RJ-45 connector and port Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
