Product information

TNS4208-8P is a high-performance Layer 3 industrial-grade Ethernet switch, equipped with 8 100/1000/2500Mbps M12 (X-coded) copper ports and supporting 8-channel PoE power supply, meeting the high reliability requirements of rail transit industrial applications. This device is specifically designed for harsh network environments, featuring M12 connectors, making it highly suitable for train/trackside, onboard, and mining application scenarios. To accommodate a broader range of usage needs, its operating temperature range extends from -40°C to 75°C.

The network management system supports multiple network protocols and industry standards, including static routing, STP/RSTP/MSTP, ERPS, 802.1Q VLAN, QoS functions, DHCP server, IGMP Snooping, LLDP, port aggregation, and port mirroring, among others. The device also provides comprehensive management functions, supporting port configuration, port statistics, port IP binding, access control, network diagnostics, quick configuration, and online upgrades; it can be accessed through multiple methods such as CLI, WEB, Telnet, SNMP, and SSH. Its user-friendly interface and simple operation deliver an exceptional user experience.

Core Advantages

Robust Power Supply: All 8 PoE ports support the IEEE 802.3af/at standard, with the entire unit delivering up to 240W of output power, ensuring stable power supply for various terminal devices.

Intelligent Management: Supports Layer 3 routing protocols such as static routing, OSPF, RIP, and VRRP (L3 models only), as well as multiple ring network redundancy mechanisms including RSTP, EAPS, and ERPS, ensuring high network availability.

Industrial-Grade Protection: Both power and data ports feature surge protection, IP40 protection rating, and a metal housing with excellent heat dissipation, adapting to harsh physical environments.

Wide Temperature Operation: Supports an operating temperature range of -40°C to 75°C, meeting the requirements of special industries such as rail transit and mining.

Typical Applications

Rail Transit (train control, trackside equipment networking)

Onboard Networks (bus and mining vehicle onboard communication systems)

Industrial Internet of Things (remote monitoring, device interconnection)

TNS4208-8P provides a secure and stable integrated solution for data transmission and power supply in industrial networks, backed by high reliability, flexible management, and robust performance.
