NIM-ES2-4 Network Interface 4-Port Gigabit Ethernet Expansion Module

The Cisco NIM-ES2-4 is a high-performance 4-port Gigabit Ethernet expansion module designed to extend the networking capabilities of compatible Cisco Integrated Services Routers (ISR). Built for branch offices, small enterprises, and remote site deployments, this expansion module adds advanced Layer 2 switching capabilities to existing ISR platforms. The NIM-ES2-4 enhances scalability and flexibility while minimizing the need for external switches, making it ideal for businesses looking to consolidate network devices, streamline performance, and simplify network management.

With support for Power over Ethernet (PoE), the module enables direct connectivity to devices like IP phones, access points, and cameras. Its compact, integrated design ensures seamless fit into supported router chassis without consuming extra rack space. Whether you’re looking to expand a small office LAN or support a multi-site deployment, the Cisco NIM-ES2-4 delivers enterprise-level features in a cost-effective form.

Features :

Designed as part of Cisco’s ISR modular architecture, the Cisco NIM-ES2-4 offers four Gigabit Ethernet ports, each capable of delivering high-throughput switching performance. This Network Interface Module (NIM) integrates directly into supported Cisco ISR 4000 Series routers, allowing you to build a unified and manageable routing and switching solution without separate hardware.

Advanced Options :

Advanced Layer 2 features such as VLAN support, QoS, and port security make the NIM-ES2-4 ideal for creating segmented and secure network environments. PoE/PoE+ support allows you to power connected endpoints directly from the router—reducing cabling complexity and enabling remote deployments where power outlets may be limited. The module is fully manageable via Cisco IOS, allowing centralized control over both switching and routing functions. This level of integration improves network visibility, simplifies troubleshooting, and streamlines configurations—all essential for dynamic business environments requiring reliability and scalability. Backed by Cisco’s renowned support and built with robust enterprise-grade hardware, the NIM-ES2-4 ensures long-term value and operational continuity.
