The Cisco IE-3500H-12FT4T-A is a purpose-built heavy-duty industrial Ethernet switch engineered for high-vibration, high-moisture, and harsh outdoor or mission-critical environments. Part of the Cisco IE3500 Rugged Series, this model delivers IP67-rated protection, M12 interfaces, and Cisco DNA/IOS XE Network Advantage capabilities—making it a superior choice for industries such as transportation, mining, manufacturing, oil and gas, and smart cities.

The switch provides 12 Fast Ethernet D-code M12 ports and 4 Gigabit Ethernet X-code M12 ports, enabling high-performance connectivity where sealed, vibration-resistant connections are mandatory.

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

FAQs About the Cisco IE-3500H-12FT4T-A

1. What makes the IE-3500H-12FT4T-A different from standard IE3500 models?
This version is built with a heavy-duty IP67 enclosure and M12 connectors, making it suitable for outdoor and high-vibration environments unlike the standard IP30 models.

2. Are the M12 D-code and X-code ports interchangeable?
No. D-code is for Fast Ethernet (10/100), while X-code supports Gigabit Ethernet (10/100/1000). They serve different cable/connector types.

3. Does the switch support Layer 3 routing?
Yes. With Network Advantage, it supports dynamic routing protocols such as OSPF, EIGRP, PIM, and VRF segmentation.

4. Can this switch be used for vehicle or railway installations?
Yes. It meets vibration and shock standards required for rail, heavy machinery, and vehicular networking.

5. Is the switch manageable via Cisco DNA Center?
Absolutely. The IE-3500H family is fully compatible with Cisco DNA Center, Industrial Network Director, and standard CLI/web management.
