Product Features
Technical Overview
This Cisco service module provides 64 dedicated asynchronous serial ports, each capable of supporting standard serial communication protocols at configurable data rates. The module integrates directly into compatible Cisco 4000 Series routers, leveraging the platform's processing power and management infrastructure for centralized control.
The physical design follows Cisco's service module form factor with precise dimensions that ensure proper fit and thermal management within the host router chassis. The module operates as a dedicated hardware component, offloading serial processing from the main router CPU to maintain overall system performance.
Key Product Advantages
The SM-X-64A= delivers concentrated serial port density in a single service module slot, optimizing router chassis utilization while simplifying cable management and reducing physical footprint compared to multiple external serial devices.
Platform Integration
Seamlessly integrates with Cisco 4000 Series router management systems, allowing unified configuration, monitoring, and troubleshooting through Cisco IOS software.
- Centralized management
- IOS command-line interface
- Integrated diagnostics
Legacy Connectivity
Maintains connectivity with serial-based equipment including console servers, industrial control systems, financial terminals, and legacy networking devices that require asynchronous serial interfaces.
- RS-232 compatibility
- Configurable data rates
- Standard serial signaling
Deployment / Use Cases
This serial service module is ideal for network environments requiring high-density serial connectivity consolidation. Common deployment scenarios include enterprise data centers managing multiple console ports for network device administration, where the module centralizes out-of-band management access.
Service providers and large enterprises utilize these modules for legacy system integration, connecting serial-based financial transaction terminals, industrial automation equipment, or telecommunications infrastructure that still relies on asynchronous serial communication. The module enables gradual migration strategies by maintaining existing serial connections while modernizing the core network infrastructure.
Console Management
Consolidate console port access for multiple network devices including switches, routers, and firewalls into a single managed interface.
Industrial Integration
Connect legacy industrial control systems, SCADA equipment, and manufacturing automation devices to modern IP networks.
