Cisco NM-1FE-TX enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco NM-1FE-TX is a single-port 10/100BASE-TX Fast Ethernet network module for the network-module slot on Cisco’s 2600, 3600 and 3700 series modular access routers. It adds one autosensing copper Ethernet interface to a router chassis, commonly used to provide a LAN uplink alongside WIC-based WAN interfaces (serial, ISDN, ADSL or E1/T1) fitted in the same router. The NM-1FE-TX sits at the entry point of the wider NM-xFE family that also includes 2- and 4-port and combination Ethernet/WAN modules for higher-density branch deployments. These routers remain in service across many established branch and small-office networks, and genuine spares such as this restore LAN connectivity after a module failure or add a port to an existing chassis. Tech-Star (UK-based, shipped worldwide) stocks Cisco network modules for engineers maintaining these platforms.
