Cisco SM-X EtherSwitch SM, Layer 2/3 switching, 16 ports GE, POE+ capable

The Cisco SM-X EtherSwitch Service Module is designed to bring high-performance Layer 2 and Layer 3 switching directly into Cisco ISR platforms, delivering a compact, power-efficient, and cost-conscious solution for modern networks. By integrating 16 Gigabit Ethernet ports with PoE+ capability into Cisco 4451-X, 3900, and 2900 Series Integrated Services Routers, this module creates a scalable LAN edge that simplifies deployment, reduces equipment footprint, and lowers total cost of ownership (TCO). It is an ideal choice for organizations seeking to consolidate switching functionality within their existing router infrastructure, while preserving the reliability, security, and management capabilities that come with Cisco IOS software and Cisco hardware ecosystem. This description blends common use cases, benefits, and technical strengths to help buyers understand how the SM-X EtherSwitch can fit into a wide range of network architectures, from branch offices to distributed enterprise campuses.

• 16 Gigabit Ethernet ports with PoE+ support. Seamlessly power and connect a mix of IP phones, wireless access points, cameras, and other PoE-capable devices directly from the ISR edge, reducing the need for separate switches and simplifying wiring closet design.
• Layer 2 and Layer 3 switching capabilities. Provides robust switching within VLANs, supports advanced traffic management, and enables routing features at the edge to optimize performance and segment networks efficiently.
• Integrated into Cisco ISR platforms. The EtherSwitch module sits in compatible Cisco routers, delivering centralized management through familiar Cisco IOS Software tools, policies, and security features for easy administration and consistent operations.
• Space-saving, energy-efficient design. By consolidating switching and routing functions into a single device, organizations gain valuable rack space and simplify power management while maintaining scalable performance as network demands grow.
• Reliable, enterprise-grade security and management. Leverage Cisco’s proven security features, QoS capabilities, and monitoring tools to protect data, prioritize critical applications, and maintain visibility across the network edge.

How to Install Cisco SM-X EtherSwitch SM

• Power down the Cisco ISR chassis and locate a supported slot for the SM-X EtherSwitch Service Module, then carefully install the module according to Cisco hardware guidelines.
• Secure the module in place and reconnect power to the router, ensuring that any required cooling is unblocked and airflow is not obstructed.
• Connect PoE+ devices to the 16 GE ports as needed. Use appropriately rated PoE devices to take full advantage of PoE+ capabilities while monitoring power budgets on the ISR.
• Power on the router and access the Cisco IOS Software CLI or GUI to initialize the EtherSwitch module. Verify that the module is recognized in the hardware inventory and that ports come online.
• Configure VLANs, QoS, security policies, and any required routing features. Create a cohesive edge policy set that matches your organization’s network design, with attention to DHCP, ACLs, and routing protocols as appropriate for your topology.
• Test connectivity and performance by simulating typical work scenarios—IP phones booting, APs stabilizing, and traffic flowing across the edge—to ensure that PoE power delivery, port forwarding, and routing behave as intended.
