4-Port Gigabit Switch Module For Cisco ISR Layer 2 LAN Expansion Cisco Module
 

The Cisco NIM-ES2-4= is a high-performance 4-port Gigabit Ethernet switch module designed for Cisco 4000 Series Integrated Services Routers (ISR). This compact yet powerful Cisco module enables seamless Layer 2 LAN expansion, making it ideal for branch offices, enterprise networks, and SD-WAN deployments. By integrating directly into the router’s Network Interface Module (NIM) slot, it eliminates the need for an external switch, reducing costs and simplifying network architecture.

Key Features & Benefits

✔ 4x Gigabit Ethernet Ports – Supports 10/100/1000 Mbps auto-negotiation for high-speed LAN connectivity.
✔ Layer 2 Switching – Enables VLANs, STP (Spanning Tree Protocol), and port aggregation for efficient traffic management.
✔ Seamless Router Integration – Plugs directly into Cisco ISR 4000 series routers (e.g., ISR 4451, 4431) without extra power requirements.
✔ Enhanced QoS & Security – Supports Cisco IOS XE for advanced Quality of Service (QoS), ACLs (Access Control Lists), and traffic prioritization.
✔ PoE Option Available – The NIM-ES2-4-P= variant provides Power over Ethernet (PoE+) for IP phones, cameras, and wireless access points.
