Cisco NM-1E is a legacy single-port Ethernet network module designed for Cisco modular access routers (such as the 2600 and 3600 series). It provides a basic 10 Mbps Ethernet LAN interface via RJ-45 or AUI connector depending on hardware revision. The module was used to expand router LAN connectivity in early enterprise and branch office networks before Fast Ethernet became standard.
It is now considered end-of-life and is primarily used in lab environments or maintaining legacy Cisco infrastructure.
