NME-X-23ES-1G Use Case
Branch Office Network Expansion with High-Density Ethernet Switching
A mid-sized retail chain deploys the NME-X-23ES-1G EtherSwitch Module on Cisco ISR routers to connect 23 PoE-powered point-of-sale terminals and IP phones across its new branch network. By leveraging 23 10/100T ports plus a dedicated 1 GE uplink, the solution delivers consistent QoS, centralized VLAN segmentation and simplified zero-touch provisioning. Outcome: 40% faster deployment, 99.99% network uptime and a 30% reduction in operational overhead.
Industrial IoT Edge Connectivity for Manufacturing Automation
A global automotive manufacturer integrates the NME-X-23ES-1G EtherSwitch into its factory-edge Cisco routers to aggregate 20+ industrial controllers, safety sensors and machine-vision cameras. The module’s deterministic 10/100T switching and 1 GE uplink ensure ultra-low-latency traffic handling, while the IP Base feature set offers granular ACL enforcement and real-time network telemetry. Outcome: 25% improvement in production cycle time, enhanced predictive maintenance and zero unplanned downtime.
Campus Network Scalability and High-Availability Uplink
A university IT team upgrades core distribution routers with the NME-X-23ES-1G EtherSwitch Module to support 23 classroom and office edge connections plus a 1 GE fiber uplink to the core. The integrated switching offloads local L2 traffic, enforces consistent security policies via Cisco IOS IP Base and enables hitless failover with redundant uplinks. Outcome: 50% reduction in cross-campus broadcast traffic, streamlined network management and guaranteed service continuity during maintenance.
