Cisco NIM-16A= 16-Port Asynchronous Network Interface Module for Cisco ISR 4000 Series Routers

Description

The Cisco NIM-16A= is a 16-port asynchronous Network Interface Module (NIM) designed for Cisco ISR 4000 Series Integrated Services Routers, providing reliable serial connectivity for legacy devices, console management, and out-of-band network access. This module enables organizations to connect multiple serial-based devices such as modems, routers, switches, PBX systems, industrial controllers, and console ports within a centralized network infrastructure.

Built with RJ-45 asynchronous serial ports, the NIM-16A= allows administrators to remotely manage networking equipment through terminal servers and console access, making it ideal for data centers, enterprise branch networks, telecommunications environments, and industrial networks where serial connectivity is still required.

The module integrates directly with Cisco IOS XE software, enabling secure remote device management through protocols such as SSH, Telnet, and console access services. It also supports advanced networking features including AAA authentication, access control lists, and centralized management, helping administrators maintain secure and efficient device management across distributed infrastructures.

The NIM-16A= module installs into the Network Interface Module slot of Cisco ISR 4000 routers, including models such as the ISR 4321, 4331, 4351, and 4431, expanding the router’s capabilities by providing multiple asynchronous serial ports for device connectivity and remote management.

Designed for scalability and reliability, the Cisco NIM-16A= offers an efficient solution for organizations that require high-density serial console connectivity while maintaining compatibility with modern enterprise routing platforms.
