<note>

The **Cisco Catalyst IE3400 Heavy Duty Switch** is built for mission-critical **Distributed Control System (DCS)
platforms**. Running **Cisco IOS XE**, this modular DIN-rail switch provides full Gigabit performance, ultra-low
latency, and up to 26 high-density ports to prevent signal bottlenecks across automated plant environments.

## Executive Summary and Core Capabilities

The **Cisco Catalyst IE3400 Rugged Series** brings intent-based enterprise networking directly to severe factory floor
environments. Designed with modular expansion capabilities, the IE3400 scales up to 26 Gigabit ports and supports
high-density Power over Ethernet Plus (PoE+) up to <span className="katex">

- **High-Density Modular Expansion:** Expand from a compact 10-port base system up to 26 ports using copper, SFP fiber,
or PoE+ expansion modules.
- **Ultra-Low Latency Determinism:** Supports IEEE 1588v2 Precision Time Protocol (PTP), CIP EtherNet/IP, and PROFINET
QoS for real-time fieldbus synchronization.
- **Resilient Ring Failover:** Features Cisco Resilient Ethernet Protocol (REP) and Spanning Tree protocols (MSTP/RSTP)
for sub-second network link recovery.
