A mid-sized financial services branch deploys a Cisco ISR equipped with NM-16ESW-1GIG-1 to terminate 16 workstations, IP phones, and networked printers on 10/100Base-T ports, while leveraging the 1 GE (1000Base-T) uplink to the corporate data center over an MPLS WAN. This consolidation replaces standalone switches and routers, reducing hardware footprint by 40%, lowering power and rack-space requirements, and centralizing network management for faster provisioning and policy enforcement.
A nationwide retail chain uses the NM-16ESW-1GIG-1 module in each store’s edge router to isolate POS terminals, inventory scanners, and back-office PCs into dedicated VLANs on its 16 10/100 ports. The single GE port uplinks encrypted traffic to the corporate HQ, ensuring separation of payment data and guest Wi-Fi. The result is simplified VLAN segmentation, compliance with PCI DSS requirements, and high-speed, secure backhaul without additional switching infrastructure.
An international law firm outfits satellite offices with Cisco routers hosting the NM-16ESW-1GIG-1 module to connect IP phones, video endpoints, and PCs on 16 FastEthernet ports. QoS policies prioritize voice and video streams, while the gigabit uplink over SD-WAN ensures low latency to headquarters. Outcomes include crystal-clear voice/video quality, streamlined deployment of unified communications, and measurable reductions in call-setup times and jitter.

The Cisco NM-16ESW-1GIG is a network module that provides 16 10/100 Ethernet switch ports and one 1 GE (1000Base-T) uplink port for compatible Cisco routers.
The NM-16ESW-1GIG is compatible with Cisco 2800, 2900, 3800 and 3900 Series Integrated Services Routers that feature an NM slot.
Power off the router, slide the NM-16ESW-1GIG into an available NM slot until it clicks, secure the captive screws, then power on and verify with the show module command.
Enter global configuration mode, select the interface range (e.g., interface range fastEthernet 0/1-16), then apply VLAN, speed, duplex, or spanning-tree settings as needed.
