The NM-1E1R2W, NM-1E2W, and NM-2E2W network modules were introduced along with the Cisco® 3600 Series in 1996. They provide Ethernet and Token Ring LAN and modular WAN connectivity options with maximum flexibility in solving branch office connectivity needs. Cisco is announcing the End of Sales of these network modules. The last sale date of the NM-2E2W is September 19, 2003. The last sale date of the NM-1E2W and NM-1E1R2W is December 31, 2003.


The recommended replacement products are the NM-1FE1R2W, NM-1FE2W-V2, and NM-2FE2W-V2. These newer LAN/WIN mixed-media network modules have a number of enhancements over the NM-1E1R2W, NM-1E2W, and NM-2E2W:

• Fast Ethernet support

• Full duplex token ring

• More WAN interface cards supported

• Higher WAN interface speeds (up to 8 Mbps)

• Supported in 2691 and 3700 Series

Details on the NM-1FE1R2W, NM-1FE2W-V2, and NM-2FE2W-V2 network modules can be found in the data sheet: (
Network applications that require the IEEE 802.3 Attachment Unit Interface (AUI) should use the NM-1E or NM-4E Ethernet network modules.

EoS refers to the time when certain products are no longer available for new purchases; it does not apply to service and support programs of the previously sold platforms. Cisco will continue to support the listed products through its SMARTnet ® and comprehensive maintenance programs. Customers with either of these service contracts are entitled to free software updates, 24-hour phone support through the Technical Assistance Center (TAC), and advanced replacement of hardware for repairs. Comprehensive maintenance customers also receive onsite service. Customers who do not have a maintenance contract can purchase software updates and hardware repair services from Cisco to meet specific requirements rather than full-service coverage.
