Cisco NM-16ESW 16-port 10/100 Ethernet Switching Network NM16ESW

Description:

The Cisco NM-16ESW Network Module is used in Cisco Integrated Services Routers to provide additional Ethernet switching capability for branch network environments. Commonly installed in enterprise branch offices, small business networks, and distributed corporate infrastructures requiring integrated Layer 2 switching within a router platform. Maintenance teams, network administrators, and system integrators use this module for network expansion, infrastructure upgrades, or replacement of existing router switching modules.

Applications:

The Cisco NM-16ESW Switching Module is deployed in branch network infrastructures to provide additional Ethernet connectivity for devices such as workstations, printers, IP phones, and other network equipment connected through a router-based switching platform. It is commonly used in branch offices, retail locations, financial institutions, and small enterprise environments where integrated switching and routing functionality are required within a single device. Network administrators and system integrators implement this module to expand LAN port capacity, simplify network architecture, and support reliable connectivity within branch network deployments.
