32 port Asynchronous Module Cisco Router Network Module
Frequently Asked Questions
What is the primary function of the Cisco NM-32A network module? +
The NM-32A is a high-density asynchronous network module designed for Cisco modular routers. It provides 32 asynchronous serial ports, making it an ideal solution for terminal server applications where you need to manage multiple console ports of networked devices, such as switches, firewalls, and routers, from a single centralized management point.
Which Cisco router platforms are compatible with the NM-32A module? +
This module is compatible with a wide range of Cisco modular access routers, including the 2600, 2800, 3600, 3700, and 3800 series. It fits into the standard network module slots found on these chassis. We recommend verifying your specific router's IOS software version to ensure it supports the necessary asynchronous line configuration commands.
What type of cabling is required to connect devices to the NM-32A? +
The NM-32A utilizes high-density cabling, typically requiring specialized breakout cables to convert the module's high-density interface into individual RJ-45 ports. These cables allow you to connect directly to the console ports of your managed equipment using standard rolled or straight-through console cables, ensuring a clean and organized rack installation.
How does the NM-32A handle asynchronous data communication? +
The module functions as a serial concentrator, supporting speeds typical for console management. By offloading asynchronous serial traffic from the router's main CPU, it allows the router to handle remote access and terminal emulation sessions efficiently. This is critical for out-of-band management, ensuring you maintain access to your infrastructure even if the primary data network experiences connectivity issues.
Does the NM-32A support modem connections for remote out-of-band access? +
Yes, the asynchronous ports on the NM-32A can be configured to support modem connections. This enables dial-up access for out-of-band management, providing a critical redundancy layer. If your primary network link fails, administrators can dial into the router via these ports to perform emergency diagnostics and restore services remotely without requiring a physical presence at the site.
How do I manage the NM-32A module once it is installed? +
Once installed, the ports on the NM-32A are managed via the Cisco IOS Command Line Interface (CLI). Each port is assigned an individual TTY line number, which you can configure for specific baud rates, parity, and stop bits. This provides granular control over each connected serial device, allowing for seamless integration into your existing network management workflows.
What are the performance limitations when using all 32 ports on the NM-32A? +
The NM-32A is designed specifically for management traffic rather than high-speed data throughput. While it supports all 32 ports simultaneously, performance is optimized for console access and terminal sessions. To ensure stability, ensure your router's processor utilization remains within acceptable limits when sessions are active on all ports, especially when performing high-volume serial data logging.
Can the NM-32A module be hot-swapped in a Cisco router? +
Most Cisco routers that support this module do not support hot-swapping for network modules while the device is powered on. You must power down the router before installing or removing the NM-32A to prevent hardware damage to the module or the router backplane. Always follow the official hardware installation guide for your specific router series before proceeding.
How can I obtain a bulk quote for multiple NM-32A modules? +
