Product Description
The SM-ES3G-24-P is a service module that adds 24 Gigabit Ethernet ports with Power over Ethernet (PoE) to Cisco 2900 Series Integrated Services Routers. It is commonly used to expand network capacity and deliver both data and power through a single module. Network administrators and IT professionals often deploy it in medium-sized enterprise environments where reliable wired connectivity and power delivery are critical. Key Features Supports Layer 3 routing for advanced network management Provides PoE to power IP phones, cameras, and wireless access points Seamlessly integrates with Cisco 2900 Series routers Enables high-speed 1 Gbps connections on all ports Offers scalable performance for growing network demands This module is typically installed in branch offices or campus networks where centralized routing and PoE capabilities simplify infrastructure. By combining switching and routing in a single device, it reduces equipment needs and cabling complexity. This makes it a practical choice for networks requiring both data transport and device powering without additional hardware.

Use Cases
The SM-ES3G-24-P module is typically installed in mid-sized enterprise branch offices or campus environments where integrated routing and switching with PoE capabilities are required. It serves IT teams managing Cisco 2900 Series routers who need to support multiple powered devices such as IP phones, wireless access points, and security cameras without deploying separate switches. How It's Used: Deploying consolidated routing and switching infrastructure in small to medium branch offices to reduce hardware footprint. Powering and connecting VoIP phones and wireless access points in corporate campus wiring closets. Supporting network segmentation and inter-VLAN routing within distributed enterprise environments. Enabling edge computing setups in retail store networks requiring both data connectivity and device power. Integrating with security systems by powering IP cameras while managing traffic through Layer 3 switching. This service module enhances operational efficiency by combining routing, Layer 3 switching, and PoE in one integrated platform, enabling scalable network growth and simplified management in environments where space and power distribution are critical.
