Key Features of the Cisco IE-3500H-12FT4T-A

Heavy-Duty IP67 Protection for Harsh Environments

The IE-3500H-12FT4T-A is designed for deployment in conditions where traditional switches fail. With an IP67 enclosure, it is fully protected against dust, water immersion, and extreme temperature fluctuations. This makes it ideal for outdoor enclosures, rolling stock, industrial vehicles, and exposed factory areas.

M12 D-code and X-code Ports for Robust Industrial Connectivity

The switch incorporates industrial-grade M12 connectors, known for their locking design and superior shock/vibration tolerance.

• 12× Fast Ethernet (10/100) M12 D-code ports for critical field devices
• 4× Gigabit Ethernet (10/100/1000) M12 X-code ports for high-bandwidth applications such as video, sensors, and controllers

These connectors ensure stable links even in environments with heavy mechanical stress.

Network Advantage License for Enterprise-Class Capabilities

Equipped with the Network Advantage feature set, this switch supports:

• Layer 3 dynamic routing (OSPF, EIGRP, BGP lite)
• VRF for network segmentation
• Advanced security policies
• High-availability protocols
• Cisco DNA Center support
• Time-Sensitive Networking (TSN) capabilities on IE3500 platform

This transforms the IE-3500H from a rugged device into a fully intelligent industrial routing and switching platform.

Extreme Temperature and Industrial Compliance

The device is tested and validated for challenging operating conditions:

• Operating temperature: –40°C to +75°C (with derating depending on mounting and power conditions)
• Vibration and shock compliance: EN, IEC, MIL-STD harsh-environment standards
• Industrially certified for transportation, railways, and automation use cases
