HWIC-4ESW Cisco 4-Ports 10/100 Ethernet Switch Wan Interface Card

HWIC-4ESW Overview

The Cisco HWIC-4ESW is a high-speed WAN interface card that enhances Cisco 2800 and 3800 Series Integrated Services Routers by adding 4 managed Fast Ethernet switch ports directly into the router chassis. This module provides integrated Layer 2 switching capabilities, enabling efficient local network expansion without requiring a separate external switch. It supports VLANs, QoS, and port-level security, allowing businesses to segment traffic, prioritize critical applications, and safeguard network access. Designed to power directly from the router HWIC slot, it is compact and space-saving while offering enterprise-class reliability.
