Cisco EtherSwitch SM-ES3-16-P Enhanced Service Module

The Cisco EtherSwitch SM-ES3-16-P Enhanced Service Module is a compact, high-value upgrade for edge networks that combines robust Ethernet switching with the reliability of Cisco IOS-driven management. Designed to drop into Cisco 3900 and 2900 Series Integrated Services Routers, this module lets you consolidate routing and switching in a single, scalable platform. By integrating Gigabit Ethernet (GE) and Fast Ethernet (FE) switch ports directly into your ISR, you can streamline network design, simplify operations, and reduce the total cost of ownership without sacrificing performance or security. Ideal for small to mid-size enterprises, branch offices, and edge deployments, the SM-ES3-16-P helps you deliver faster LAN access, improved traffic control, and dependable connectivity to users, devices, and applications across your organization.

• Seamless integration of Gigabit Ethernet and Fast Ethernet switch ports into Cisco 3900 and 2900 Series Integrated Services Routers for unified routing and switching at the network edge.
• 16-port Ethernet switching capability in a single Enhanced EtherSwitch Service Module, offering flexible port configurations to support growing networks and multiservice applications.
• Cisco IOS-based management with built-in features such as VLAN segmentation, quality of service (QoS), and basic security controls to optimize traffic flows and protect critical data.
• Cost-efficient deployment that reduces cabling complexity, minimizes energy use, and eliminates the need for separate switches, helping to lower total cost of ownership while preserving existing Cisco infrastructure investments.
• Reliability and ease of maintenance with a hot-swappable design (where supported by the chassis) and a compact form factor that fits neatly into ISR slots, enabling quick swaps with minimal downtime in busy networks.

Technical Details of Cisco EtherSwitch SM-ES3-16-P Enhanced Service Module

• Product type: Enhanced EtherSwitch Service Module (SM-ES3-16-P)
• Router compatibility: Cisco 2900 Series and Cisco 3900 Series Integrated Services Routers
• Ports: 16 integrated Ethernet ports (supporting Fast Ethernet and Gigabit Ethernet capabilities as configured by the module)
• Switching features: VLAN support, basic bridging, and QoS capabilities integrated with IOS-based management
• Form factor: Service Module designed for insertion into supported Cisco ISR chassis slots

How to Install Cisco EtherSwitch SM-ES3-16-P

• Verify compatibility: Confirm your Cisco ISR model (2900 or 3900 series) and available service module slot are suitable for the SM-ES3-16-P, and review Cisco installation guidelines for hot-swappable modules.
• Prepare the chassis: Ensure adequate airflow and clearance around the router rack, and power down the device if your installation procedure requires it (or follow your data center’s hot-swappable protocol if supported).
• Remove the blank or existing module: If the intended slot is occupied, carefully remove the current module or blank panel according to the device’s maintenance procedures to expose the slot.
• Insert the SM-ES3-16-P: Align the module with the slot’s connectors, slide it in firmly, and seat it until it’s securely seated. If your chassis supports hot-swapping, you may be able to insert with the router powered; otherwise follow standard shutdown procedures.
• Reconnect cables and power: Attach your Ethernet cables to the ports on the SM-ES3-16-P as required by your network design. Restore power and allow the router to initialize the new module.
• Configure via Cisco IOS: Access the router’s IOS interface and configure the switched ports, VLANs, and QoS policies as needed. Define port modes (access/trunk), assign VLANs, and apply security and quality policies to match your network requirements. Validate connectivity and monitor performance to ensure the new module operates as intended.
