By combining industrial-grade durability with intelligent network management, the TN-5516-8POE switches provide a reliable platform for transportation networks and other challenging industrial environments.

Industrial-Grade Design and EN 50155 Compliance

The TN-5516-8POE series is engineered to withstand harsh industrial conditions, including extreme temperatures, vibration, and electrical noise. Adhering to the EN 50155 standard ensures that these switches are suitable for railway rolling stock and other transportation applications where reliability and safety are critical. EN 50155 certification guarantees that the device operates within a wide temperature range, maintains power stability under transient voltage conditions, and resists mechanical shocks and vibration, making it ideal for deployment in trains, subways, and other high-demand transit systems.

Temperature Range and Environmental Tolerance

Designed for extreme industrial environments, the TN-5516-8POE switches can operate in a wide temperature range from -40°C to 75°C. This broad operating range ensures consistent network performance in both outdoor and indoor scenarios, whether in cold climates or high-temperature zones near mechanical or electrical equipment. The rugged housing, combined with conformal coating on internal PCBs, protects against dust, moisture, and corrosive elements, significantly extending the operational lifespan of the switch.

Port Configuration and IEEE 802.3af PoE Support

The TN-5516-8POE features 16 total Ethernet ports, of which 8 provide IEEE 802.3af Power over Ethernet. This capability eliminates the need for separate power cabling for connected devices, simplifying installation and reducing infrastructure costs. PoE support is critical in scenarios such as IP surveillance systems, Wi-Fi access point deployment, and intercom systems, where devices require both data connectivity and reliable power. Each PoE port intelligently negotiates power requirements to prevent overload and maximize energy efficiency across all connected devices.

Power Management and Load Distribution

The managed nature of the TN-5516-8POE allows precise power management and allocation. Network administrators can monitor and configure PoE settings for each port individually, optimizing energy usage and ensuring uninterrupted service for critical devices. Advanced PoE features include real-time power consumption monitoring, automatic port shutdown in case of overload, and prioritization of essential devices. This ensures that in high-demand scenarios, vital network endpoints continue to receive power without interruption.

Advanced Network Management Features

The TN-5516-8POE is a fully managed switch, providing extensive configuration and monitoring capabilities that are essential for industrial networks. Key management protocols include SNMPv1/v2c/v3, RMON, IEEE 802.1Q VLAN, IEEE 802.1p QoS, and IGMP snooping. These features allow network administrators to segment traffic, prioritize critical data streams, and reduce broadcast storms, enhancing overall network reliability and performance.

VLAN and Traffic Segmentation

Virtual LAN (VLAN) support on the TN-5516-8POE enables logical segmentation of the network, allowing operators to separate control, surveillance, and passenger Wi-Fi traffic. This segmentation reduces congestion and increases security by isolating sensitive operational data from general-purpose network traffic. VLAN configuration is fully manageable through the web interface or command-line interface (CLI), providing flexibility in complex deployments.

Quality of Service and Traffic Prioritization

With IEEE 802.1p-based Quality of Service (QoS), the TN-5516-8POE ensures that high-priority traffic, such as real-time video from IP cameras or voice over IP, is transmitted without delay. The switch can classify and prioritize packets based on port, VLAN, or traffic type, maintaining consistent performance for mission-critical applications in congested network environments. This is particularly important in railway and transportation systems where low-latency communication is crucial for operational safety.

Redundancy and Reliability in Industrial Networks

The TN-5516-8POE provides multiple redundancy protocols to ensure uninterrupted operation even in the event of network faults. It supports Rapid Spanning Tree Protocol (RSTP), MSTP, and Turbo Ring redundancy, allowing network designers to create resilient topologies with minimal downtime. Turbo Ring technology, specific to Moxa devices, enables sub-20ms recovery times in ring network configurations, ensuring continuous operation for critical transit systems where network failures can lead to significant service disruption.

Ring and Mesh Topologies

By leveraging ring and mesh network topologies, the TN-5516-8POE minimizes single points of failure. Ring topology allows automatic rerouting of traffic if a link fails, while mesh topology provides multiple paths for data to travel, further enhancing reliability. These redundancy mechanisms are essential for industrial applications, where downtime can lead to operational delays and safety risks. Network monitoring tools integrated with the switch allow administrators to detect and address faults in real time, maintaining seamless connectivity.

Security and Network Protection

In addition to robust network management, the TN-5516-8POE incorporates advanced security features. These include port security, MAC address filtering, 802.1X authentication, and access control lists (ACLs). By implementing strict security measures, the switch prevents unauthorized access, mitigates network attacks, and ensures that sensitive operational data remains protected. Industrial networks, especially in transportation and critical infrastructure, require these security features to maintain regulatory compliance and operational integrity.

Port Security and Access Control

Port security allows administrators to define which devices are permitted to connect to each port, preventing rogue devices from joining the network. MAC address filtering provides an additional layer of control by limiting connections based on recognized hardware addresses. Together with ACLs and 802.1X authentication, these features safeguard the network from unauthorized access while maintaining seamless communication for approved devices. This combination of physical and logical security measures ensures operational safety and continuity.

Ease of Deployment and Maintenance

The Moxa TN-5516-8POE is designed for ease of installation and maintenance in industrial environments. Its compact form factor fits standard DIN-rail mounting systems, while a wide input voltage range supports both DC and AC power supplies. Web-based management interfaces and CLI tools simplify configuration, firmware updates, and ongoing monitoring, allowing network engineers to maintain the network efficiently without requiring specialized tools. Additionally, LED indicators provide visual confirmation of port status, link activity, and PoE operation, enabling quick diagnostics in the field.

Integration with Existing Infrastructure

The TN-5516-8POE integrates seamlessly into existing industrial networks, supporting a wide range of Ethernet standards and backward compatibility with previous Moxa switch generations. Its compatibility with SNMP-based network monitoring tools allows integration with centralized management platforms, providing administrators with a unified view of the network. This reduces operational complexity and ensures smooth coordination with other network equipment, from routers and wireless access points to industrial controllers.
