Cisco EHWIC-D-8ESG 8 Port Gigabit Enhanced WAN Interface EHWIC Card fast ship EHWICD8ESG

Description:

The Cisco EHWIC-D-8ESG Enhanced High-Speed WAN Interface Card is a modular expansion card designed for Cisco Integrated Services Routers to provide additional Gigabit Ethernet switching capability within enterprise branch network infrastructures. It features eight Gigabit Ethernet ports that allow routers to function as integrated switching platforms, enabling local network connectivity and simplified infrastructure deployment in branch offices. Built for Cisco ISR platforms, this EHWIC module integrates switching functionality directly into the router chassis, reducing the need for separate external switches in smaller network environments. Commonly installed in Cisco ISR routers used in corporate branch offices, retail networks, and distributed enterprise locations where additional Gigabit Ethernet ports and integrated switching functionality are required. Maintenance teams, network administrators, and system integrators deploy this module for router interface expansion, network upgrades, infrastructure consolidation, or replacement of existing router switching modules. 

Applications:

The Cisco EHWIC-D-8ESG module is used in enterprise branch networking environments to provide integrated Gigabit Ethernet switching directly within Cisco Integrated Services Routers. It is commonly deployed in branch offices, retail locations, small business networks, and distributed enterprise sites where additional LAN ports are required for connecting workstations, IP phones, wireless access points, and other network devices. Network engineers install this module to extend router connectivity, simplify network infrastructure, and support local switching capabilities without requiring separate external switching hardware.
