Cisco NM-32A enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco NM-32A is a 32-port asynchronous network module for Cisco’s modular access router and access-server platforms, including the 2600, 3600 and AS5300-class chassis where fitted. Each port provides a standard RS-232 asynchronous serial connection, typically used for console/terminal server aggregation, dial-in/dial-out modem banks, or connecting legacy serial devices in bulk, rather than for WAN routing. High-density async modules like this were a common way to build a low-cost terminal server or reverse-Telnet console-access box on standard router hardware rather than dedicated access-server equipment. It remains a routine spare for existing console-server or async-aggregation deployments still in service. Confirm your target router platform and available network-module slot before ordering, since NM form factor and power budget vary across compatible platforms. This is a refurbished unit, shipped worldwide from Tech-Star’s UK stock.
