SM-D-ES3G-48-P Cisco 48-Port Gigabit Ethernet PoE Switch Module

The SM-D-ES3G-48-P is a Cisco Ether Switch Service Module that adds 48 Gigabit Ethernet ports with Power over Ethernet capability. Commonly used in enterprise network environments, it integrates directly into compatible Cisco routers to enhance network access and simplify infrastructure.

Built for network administrators and IT professionals, this module streamlines connectivity by combining switching and routing into a single device. It's often found in medium to large office networks where reliable, high-speed connections and PoE power for devices like IP phones and wireless access points are needed.

Key Features

• Offers 48 Gigabit Ethernet ports with PoE to power connected devices
• Seamlessly integrates into Cisco router chassis for consolidated management
• Delivers high throughput to support demanding network applications
• Supports Cisco IOS software for flexible configuration and control
• Enables simplified cabling and reduced hardware footprint

This service module is typically deployed inside Cisco Integrated Services Routers, providing network edge switching capabilities without additional standalone switches. By consolidating functions, it helps reduce space and energy use while maintaining robust network performance.

Its role in powering endpoint devices directly through Ethernet cabling also reduces the need for separate power sources, simplifying installation and maintenance across office networks.
