Cisco EHWIC-4ESG-P EHWIC-4ESG Four port 10/100/1000 POE SWITCHING INTERFACE MDL EHWIC4ESGP

Description:

The Cisco EHWIC-4ESG-P Enhanced High-Speed WAN Interface Card is a modular switching interface designed for Cisco Integrated Services Routers to provide additional Gigabit Ethernet connectivity with integrated Power over Ethernet (PoE) capabilities. It features four 10/100/1000 Gigabit Ethernet ports that allow routers to function as compact switching platforms capable of delivering both network connectivity and electrical power to connected devices such as IP phones, wireless access points, and IP surveillance cameras. Designed for Cisco ISR platforms, this module integrates switching and PoE functionality directly into the router chassis, enabling simplified branch network deployments without the need for separate external switches. Commonly installed in Cisco Integrated Services Routers used in branch offices, retail networks, and distributed enterprise environments where additional Ethernet ports and PoE-powered device support are required. Maintenance teams, network administrators, and system integrators deploy this module for router interface expansion, PoE device connectivity, infrastructure upgrades, or replacement of existing router switching modules.

Applications:

The Cisco EHWIC-4ESG-P module is used in enterprise branch networking environments to provide integrated Gigabit Ethernet switching with PoE capability directly within Cisco Integrated Services Routers. It is commonly deployed in branch offices, retail stores, remote enterprise locations, and small business networks where additional LAN ports and power delivery for network devices are required. Network engineers install this module to connect IP phones, wireless access points, and surveillance cameras while expanding router-based network infrastructure and reducing the need for additional external switching equipment.
