Applications
The NM-1E1R2W was deployed in Cisco 3600 router environments during the late 1990s and early 2000s, when many networks still relied on Token Ring alongside emerging Ethernet standards. This module is commonly used in network modernization projects involving legacy Cisco routers, where organizations need to maintain connectivity to existing Token Ring networks while adding Ethernet and serial WAN capabilities. The dual-interface design allows administrators to select the appropriate protocol without requiring module replacement. These cards remain valuable for supporting older network segments, educational settings studying network history, or maintaining legacy systems that cannot yet be fully migrated to modern Ethernet-only infrastructure.
This Cisco NM-1E1R2W mixed-media network module has been inspected and is in good used condition. It was pulled from a working environment where it was previously in service. The module features one Ethernet interface with both 10BaseT and AUI ports (selectable), one Token Ring interface with both DB-9 and RJ-45 ports (selectable), and two WAN Interface Card (WIC) slots for expanding connectivity options. Compatible with Cisco 3600 Series routers. Please view our photo set and contact us if you have any questions.
