Description:

The Cisco HWIC-4ESW-POE Ethernet Switch Interface Card is used in Cisco Integrated Services Routers to provide four-port Ethernet switching with integrated Power over Ethernet capability for connected network devices. Commonly installed in Cisco 1800, 2800, and 3800 Series router deployments used in enterprise branch offices, small business networks, and remote site infrastructures where routers require additional switching ports and PoE support. Maintenance teams, network administrators, and system integrators use this interface card for router port expansion, infrastructure upgrades, replacement of failed modules, and deployment of integrated switching functionality within Cisco router platforms. 

Applications:

The Cisco HWIC-4ESW-POE module is deployed in enterprise and branch networking environments where routers require integrated Ethernet switching and PoE support for connected devices. It is commonly used in branch offices, remote enterprise locations, and small office networks where routers must support devices such as IP phones, wireless access points, and security cameras. Network administrators install this module in compatible Cisco Integrated Services Routers to expand switching capacity and provide both connectivity and electrical power to Ethernet-enabled devices.
