Cisco Catalyst IE3400 Heavy‑Duty Series – Fanless, IP67‑Rated Switches for Extreme Industrial Connectivity

Need reliable networking beyond the office—across factories, mines, stadiums, or farms—where dust, water, and extreme temperatures prevail? The Cisco Catalyst IE3400 Heavy‑Duty Series delivers exactly that.

At Cisco Live US, we unveiled these rugged switches in a live demo that showcased their water‑resistance. Visitors watched a continuous stream of water pass over the device while it maintained flawless performance. If you missed the event, view the video below.

The IE3400 is IP67‑rated, meaning it’s fully dust‑tight and can withstand immersion in water up to 1 m for 30 minutes. It operates reliably from –40 °C to 75 °C, has no fans for silent operation, and supports key industrial protocols such as Modbus, OPC, and MQTT.

Because it’s fanless and self‑contained, the switch can be installed directly on machinery or in a harsh environment—no cabinet needed.

Powered by Cisco IOS XE, the same next‑generation operating system found on flagship Catalyst switches, the IE3400 offers enterprise‑grade security and edge computing capabilities right at the plant floor.

• Enterprise‑grade security – Cisco Trustworthy solutions, software‑based segmentation, and real‑time flow visibility help detect threats and isolate vulnerable endpoints, whether they’re PLCs, sensors, or drives.
• Unified management – Control OT and IT networks from a single pane with Cisco DNA Center, or use Cisco Industrial Network Director for industrial‑specific orchestration.
• Port flexibility – Choose from 8‑, 16‑, or 24‑port models, all Fast Ethernet or all Gigabit. Opt for Fast Ethernet for brownfield deployments or Gigabit to future‑proof greenfield projects.
• Edge compute ready – Hardware supports Docker and the latest edge‑compute innovations, enabling lightweight containerized services directly on the switch.
