Description:

The Cisco NME-16ES-1G-P EtherSwitch Service Module is a network switching module designed for Cisco Integrated Services Routers to provide integrated Ethernet switching and Power over Ethernet (PoE) capabilities within enterprise branch network infrastructures. It features 16 Fast Ethernet PoE ports along with Gigabit uplink interfaces, enabling routers to function as compact switching platforms capable of supporting both network connectivity and powered network devices. Built for Cisco ISR platforms, this service module integrates switching functionality directly into compatible router chassis to simplify branch network deployments and reduce the need for separate external switches. Commonly installed in Cisco routers such as the 2811, 2821, 2851, and 3825 used in corporate branch offices, retail networks, and distributed enterprise environments where additional LAN switching and PoE device support are required. Maintenance teams, network administrators, and system integrators deploy this module for router switching expansion, PoE device connectivity, infrastructure upgrades, or replacement of existing router service modules. 

Applications:

The Cisco NME-16ES-1G-P module is used in enterprise branch networking environments to provide integrated Ethernet switching with Power over Ethernet directly within Cisco Integrated Services Routers. It is commonly deployed in branch offices, retail stores, financial institutions, and distributed enterprise locations where additional LAN ports and power delivery for network devices are required. Network engineers install this module to connect IP phones, wireless access points, and other Ethernet devices while expanding router-based network infrastructure and simplifying branch network architecture without requiring separate external switches.
