The Cisco IE-3100-8T2C-E is a rugged industrial Ethernet switch designed to deliver secure, reliable, and high-performance network connectivity for harsh industrial environments. Built to support industrial automation, manufacturing, transportation, energy, mining, and smart infrastructure applications, it features 8 Gigabit Ethernet RJ45 ports and 2 combo Gigabit uplink ports (RJ45/SFP), providing flexible copper or fiber connectivity for seamless network expansion. Engineered with an industrial-grade design, the IE-3100-8T2C-E operates reliably under extreme temperatures, vibration, and electrical interference while ensuring continuous operation in mission-critical environments. It supports advanced Layer 2 switching features, comprehensive security capabilities including IEEE 802.1X authentication, Access Control Lists (ACLs), MACsec encryption, Secure Boot, and Trust Anchor technologies, helping protect industrial networks from cyber threats. With support for Quality of Service (QoS), VLANs, Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP), Link Aggregation (LACP), IGMP Snooping, and industrial redundancy protocols, the switch delivers optimized traffic management, high network availability, and minimal downtime. Cisco DNA Center and Cisco Industrial Network Director (IND) compatibility simplify deployment, monitoring, and lifecycle management, reducing operational complexity for IT and OT teams. The Cisco IE-3100-8T2C-E also supports Power over Ethernet management integration, industrial automation protocols, and scalable network architectures, making it an ideal solution for building secure, resilient, and future-ready industrial Ethernet networks. Whether deployed in factory production lines, utility substations, intelligent transportation systems, oil and gas facilities, or remote industrial sites, the Cisco IE-3100-8T2C-E provides enterprise-class performance, long-term reliability, and simplified network management to meet the evolving demands of Industrial IoT (IIoT) and digital transformation initiatives.
