Attach either one or two Fast Ethernet/Ethernet 10/100 cables to the Fast Ethernet/Ethernet port 0 or port 1.

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.

Attaching the GBIC Interface Cables

The GBIC ports support IEEE 8092.3z (optical Gigabit Ethernet) interfaces compliant with 1000BASESX and 1000BASELX specifications.

After you install the GBIC in the Gigabit Ethernet port, you must attach the cables to the GBIC. The instructions that follow apply to all supported platforms.

See Appendix A, “Specifications,” for more information on GBIC cabling and cabling specifications.

Note Optical fiber cables are commercially available; they are not available from Cisco Systems.

Attaching Multimode and Single-Mode Optical Fiber Cables

If you ordered a Gigabit Interface Converter (GBIC) with your Cisco 7401ASR router, it is one of three types listed in Table 2-4:
