(See Figure 2-9.) The top port is marked Port-1 on the module, and the lower port is marked Port-0. On the dual-port Ethernet network processor module, on a given port, either the Ethernet connector or the 10BaseT connector can be used, but not both. For example, Ethernet port 0 could be attached to either a 10BaseT connector or to an AUI connector, and similarly Ethernet port 1 could be attached to either a 10BaseT connector or to an AUI connector. 2-12 Cisco 4000 Series Hardware Installation and Maintenance
