Cisco Catalyst IE-3100-18T4S-E Rugged Fanless Industrial Layer 2 / Lite Layer 3 Switch, 18×10/100/1000BASE-T Non-PoE Gigabit Downlinks, 4×Dedicated Gigabit SFP Fiber Uplink Ports, Cisco IOS XE Network Essentials Software, Extended Wide Temperature Hardened DIN-Rail Mount Switch, High Fiber Density Optimized for Large Factory Automation, Smart City Mass Surveillance, Mining, Oil & Gas and Power Substation Mission-Critical OT Networks

2. Official Product Overview

The Cisco Catalyst IE-3100-18T4S-E is a high-port-density fanless hardened Layer 2 / Lite Layer 3 industrial switch from Cisco Catalyst IE3100 Rugged Series, built for large-scale edge OT deployments requiring abundant Gigabit copper downlinks plus four independent fiber-only uplink ports without shared combo RJ45 media limitations. It is the extended-temperature hardened variant engineered for stable long-term continuous operation inside fully sealed unventilated industrial enclosures with extreme hot/cold swings, heavy dust, high humidity and strong substation-grade electromagnetic interferenceCisco.

Model Suffix Breakdown

18T: Eighteen 10/100/1000BASE-T Gigabit RJ45 copper downlink ports, non-PoE unpowered interfaces
4S: Four independent dedicated Gigabit SFP fiber uplink slots (pure fiber-only, no shared combo RJ45 media)
E: Extended wide-temperature hardened chassis with reinforced PCB thermal layout, validated for reliable continuous operation inside zero-airflow sealed cabinets

This industrial switch features IP30 metal fanless passive convection cooling chassis, dual redundant isolated DC power inputs, high-grade reinforced EMC/EMI surge filtering, and extended thermal tolerance superior to standard-temperature IE3100 SKUs. Fanless zero-moving-part design eliminates fan failure risks and cuts long-term maintenance workload for remote unmanned roadside, mining and power substation cabinets. Four standalone SFP uplinks enable multi-fiber trunking, redundant ring topologies and multi-path backbone connections to multiple control room core switches without sacrificing copper uplink ports.

Preloaded universal Cisco IOS XE Network Essentials firmware with native IEEE 1588v2 PTP precision timing, it natively supports critical industrial automation standards: REP Resilient Ethernet Protocol, MRP Media Redundancy Protocol, EtherNet/IP, PROFINET and Modbus TCP; built-in L2 NAT enables cross-subnet remote site IP translation without extra license upgrades, plus static Lite Layer 3 IPv4 routing for inter-VLAN forwarding.

Powered by industrial-grade high-speed chipset, 1GB DRAM and front-access removable SD flash storage, it delivers 22 Gbps non-blocking switching capacity and 16.4 Mpps wire-speed forwarding rate for 64-byte frames. Low-latency optimized packet buffering ensures consistent transmission of real-time PLC motion control signals, mass multi-stream industrial surveillance video and high-volume distributed IIoT sensor data. Passive heat sink fanless design enables silent, maintenance-free 24/7 continuous operation in sealed enclosures.
