The Antaira LMX-1802G-M12-10G-SFP-67-110-T is an 18-port industrial Ethernet switch designed to connect, manage and power the most demanding onboard rail applications. Combining M12 connectivity, IP67 water- and dust-resistant protection, Light Layer 3 management, and dual 1G/10G SFP+ uplinks, this next-generation switch sets a high standard for railway network reliability and performance.

Built for the unforgiving conditions of modern rail transit, the LMX-1802G-M12-10G-SFP-67-110-T delivers fail-safe networking that keeps critical systems operational even when components fail. The integrated bypass function ensures continuous network availability—a game-changing feature for mission-critical applications where downtime isn’t an option.

Meeting Extreme Demands of Modern Rail Networks

Today’s rolling stock demands more from network infrastructure than ever before. The LMX-1802G-M12-10G-SFP-67-110-T directly addresses four critical requirements that define rail connectivity:

High-Speed Network Connectivity: Dual 1G/10G SFP+ slots provide flexible, high-bandwidth uplinks for data-intensive onboard systems, from 4K passenger information displays to HVAC monitoring and streaming entertainment services. Sixteen Gigabit M12 ports (10/100/1000Tx, X-coded) supply high-speed performance across all connected devices. Vibration-resistant M12 connectors maintain signal integrity through the constant motion and mechanical stress of rail operation.

Network Redundancy: Intelligent bypass technology automatically reroutes traffic around failed devices, ensuring passenger information displays, safety systems, and critical infrastructure maintain 100% uptime regardless of individual component failure.

Extreme Environment Operation: An IP67 metal housing and wide-temperature performance (-40°C to +70°C) secure reliable operation through onboard extremes including vibration, shock, and exposure to moisture, dust, and contaminants inherent to rail environments.

Mixed Infrastructure Support: The switch seamlessly powers PoE-enabled devices such as security cameras and wireless access points while simultaneously supporting non-PoE devices. It can be connected to HVAC controllers, LED information displays, smoke detectors, onboard lighting systems, and paging equipment—all from a single unified 18-port platform.

Enterprise-Grade Network Management

The LMX-1802G-M12-10G-SFP-67-110-T transforms network reliability from a goal into a guarantee with comprehensive security and management capabilities including:

• Multi-user account management with role-based access control
• IGMP snooping for optimized multicast traffic handling
• ITU-T G.8032 ERPS v2 protocol provides sub-50ms failover for carrier-grade redundancy
• Advanced VLAN and GVRP support for network segmentation
• Quality of Service (QoS) prioritization for latency-sensitive applications
• SNMP monitoring with RADIUS and TACACS+ authentication
• Port aggregation (Static and LACP) for enhanced bandwidth and redundancy
• Encrypted management via SSH and SSL
• IP source guard for enhanced security posture

PoE+ Power Delivery Simplifies Installation

Integrated PoE+ capability supplies up to 30W per port, eliminating the need for separate power infrastructure for IP cameras, wireless access points, and other powered devices. This reduces installation complexity, cuts deployment costs, and enhances system reliability by centralizing power management.

Railway-Certified for Mission-Critical Deployment

The LMX-1802G-M12-10G-SFP-67-110-T carries complete railway certification credentials, including EN50155 (railway applications), EN50121-3-2 (EMC emissions), and EN50121-4 (EMC immunity). These certifications guarantee compliance with international standards for electrical safety, electromagnetic compatibility, and environmental performance in rolling stock applications.
