Token Ring Network Modules Chapter 3 Connecting Ethernet, Fast Ethernet, and Token Ring Network Modules Fast Ethernet LEDs This section describes Fast Ethernet module LEDs. Figure 3-19 shows 1-port Fast Ethernet network module LEDs as an example. Figure 3-19 1-Port Fast Ethernet Network Module LEDs FAST ETHERNET 1FE 10/100 bTX EN COL LINK 100 MBPS FULL DPLX H9982 LEDs Enable LED All network modules have an enable (EN) LED. The enable LED indicates that the module has passed its self-tests and is available to the router. Fast Ethernet network modules have the additional LEDs shown in Table 3-1. Table 3-1 Fast Ethernet Network Module LEDs LED COL LINK 100MBPS FULL DPLX Meaning Collision activity is occurring on the network. A link has been established with the station at the other end of the cable. Speed of the interface is 100 Mbps. Interface is in full-duplex mode. Token Ring Network Modules The following network modules provide Token Ring interfaces: • 1-port Ethernet 1-port Token Ring 2-WAN card slot module (NM-1E1R2W) (see Figure 3-20) • 1-port Fast Ethernet 1-port Token Ring 2-WAN card slot module (NM-1FE2R2W) (see Figure 3-21) 3-10 Cisco Network Modules Hardware Installation Guide OL-2485-20
