Cisco EHWIC-4ESG-P 4-Port Gigabit Ethernet Switch Interface Card with PoE

Description

Enhance your Cisco Integrated Services Router (ISR) with the Cisco EHWIC-4ESG-P, a high-performance 4-port Gigabit Ethernet switch interface card designed to provide additional LAN connectivity and Power over Ethernet (PoE) capabilities in a compact module.

Engineered for Cisco ISR G2 platforms, the EHWIC-4ESG-P integrates a managed Layer 2 Ethernet switch directly into your router, eliminating the need for a separate standalone switch in many branch office deployments. Each of the four RJ-45 ports supports 10/100/1000 Mbps auto-negotiating Ethernet, ensuring compatibility with a wide range of network devices including computers, IP phones, wireless access points, IP cameras, and printers.

With IEEE 802.3af Power over Ethernet (PoE) support, the module can deliver power and data over a single Ethernet cable to compatible devices, simplifying installation, reducing cable clutter, and lowering infrastructure costs.

The integrated switch supports essential Layer 2 networking features including VLANs, Quality of Service (QoS), Spanning Tree Protocol (STP), port security, and traffic prioritization, enabling efficient and secure network operation for business environments.

Designed specifically for Cisco ISR G2 routers, the EHWIC-4ESG-P offers centralized management through Cisco IOS Software, allowing administrators to configure and monitor switching functions using familiar Cisco management tools.

Whether you’re expanding a branch office, deploying IP telephony, or supporting wireless access points, the Cisco EHWIC-4ESG-P provides a flexible, reliable, and enterprise-class networking solution.
