NM-32A Use Case
Out-of-Band Management for Multi-Vendor Data Centers
In large data centers supporting multi-vendor infrastructure, IT teams need secure, reliable console access to every switch, firewall and server for maintenance and troubleshooting. Deploying the Cisco NM-32A 32-port Asynchronous Module in an ISR router delivers 32 dedicated serial console ports over an isolated management network. This enables centralized, encrypted CLI access, rapid firmware upgrades and automated failover testing without impacting production traffic. Benefit: Minimizes downtime, strengthens security and streamlines network operations.
Serial Connectivity for Remote Industrial Automation
Distributed manufacturing plants often depend on legacy PLCs, HMIs and SCADA controllers with RS-232/RS-422 interfaces for critical process control. By installing the Cisco NM-32A 32-port Asynchronous Module on an ISR router, operators can aggregate serial equipment and encapsulate data over IP tunnels for real-time monitoring. This solution reduces latency, improves reliability and simplifies remote diagnostics via a single management plane. Benefit: Maximizes port density, lowers CAPEX and enhances operational visibility.
Branch Office WAN Backup and POS Terminal Support
Retail and hospitality chains require uninterrupted connectivity for point-of-sale (POS) devices and ATMs in branch locations. The Cisco NM-32A 32-port Asynchronous Module enables direct serial attachment of up to 32 POS terminals or dial-up backup links in a single router slot. This ensures continuous transaction processing during primary WAN failures and consolidates terminal management. Benefit: Guarantees business continuity, reduces revenue loss and centralizes network operations.

How do I install the NM-32A module in my Cisco router?
Power down the router, unlock and remove the blank slot cover, slide the NM-32A into the slot until it clicks, secure the module with the retention screw, then power up the router.
What cable types are supported by the NM-32A module?
The NM-32A supports standard RJ-45 to DB25 or RJ-45 to RJ-48 cables for asynchronous and synchronous serial connections.
How do I configure serial ports on the NM-32A in IOS?
Enter interface configuration mode (e.g., interface async 0/0/0), set encapsulation and line parameters (e.g., encapsulation ppp, speed 115200), then apply dialer or async profile commands.
What throughput can I expect from each port on the NM-32A?
Each asynchronous port supports up to 115.2 Kbps, subject to overall router backplane capacity and IOS processing overhead.
