Product Features
Technical Overview
The EHWIC-4ESG-P-RF implements Gigabit Ethernet technology across four independent RJ-45 ports, each supporting 10/100/1000Base-T auto-negotiation. All ports deliver Power over Ethernet according to IEEE 802.3af/at standards, providing up to 30W per port for connected devices.
The module's compact form factor measures 3.10" wide by 4.80" deep with a height of 0.80", making it suitable for installation in Cisco ISR router slots. With a weight of approximately 108 grams, it adds minimal physical load while delivering substantial network expansion capability.
Key Product Advantages
High-Density PoE Deployment
Four independent PoE ports enable simultaneous power delivery to multiple network devices, reducing the need for separate power injectors and simplifying cable management in distributed deployments.
Backward Compatibility
Full compatibility with existing Category 6 cabling infrastructure ensures seamless integration without requiring cable plant upgrades, protecting previous investments while enabling Gigabit performance.
Enterprise-Grade Reliability
Refurbished to Cisco standards with 90-day warranty coverage, this WIC module delivers reliable performance for business-critical WAN connections while offering significant cost savings over new units.
Deployment / Use Cases
The EHWIC-4ESG-P-RF serves as an ideal expansion module for branch office routers requiring additional WAN interfaces with PoE capability. Its four-port configuration supports scenarios where multiple dedicated WAN links or backup connections are necessary for business continuity.
Common deployment scenarios include connecting to multiple ISP circuits for load balancing, establishing VPN tunnels across diverse network paths, or providing PoE to security cameras and access points at remote sites. The module's Gigabit throughput ensures sufficient bandwidth for modern business applications and cloud services.
Branch Office Connectivity
Expand WAN capacity at remote locations with multiple dedicated internet circuits or MPLS links while powering local network devices through the same interface card.
Service Provider Edge
Deploy in aggregation routers to provide multiple customer-facing WAN ports with PoE for managed service offerings, reducing equipment footprint at customer premises.
