The switch supports Layer 2 management, NAT, advanced security functions, and onboard network deployment with WebGUI and comprehensive CLI for straightforward configuration. Its OPEN API in Restful format enables efficient central management, making it suitable for applications such as fleet management and AIoT. Advanced cybersecurity mechanisms protect against hacking and network attacks. Compliance with EN50155, ITxPT*, and E-marking* certifications ensures the product meets world-class standards for reliability and performance in vehicle and rail applications.

Redundant dual power input design ; EN50155 verification with high ESD and inrush current prevention and reverse polarity protection; E-marking & ITxPT* certificate; ISO 16750-2 P5A compliant
T(P)GR-3208T-WEB is designed with dual power inputs that accept 9V~36V DC for 24VI vehicle use and is capable of withstanding EMI/RFI interference in the onboard network as well as environmental shocks and vibrations. The redundant power input design integrates inrush current protection also protect against polarity reversal. Additionally, the galvanic isolation feature shields the system from power transients often present in onboard networks. The switch complies with ITxPT* public transport standards and E-marking*. It also meets the requirements of ISO 16750-2 P5A, reducing the impact of high-frequency pulse voltage that could be incurred by motor applications.

Support Perpetual*/Fast PoE*; PoE budget up to 80W for 8 Ports with PD detection, auto PD reboot, scheduling and Ethernet power input galvanic isolation with partial ports for PoE galvanic isolation
Fast PoE* and Perpetual PoE* combined provide uninterrupted power delivery for critical devices. Fast PoE instantly supplies power after startup, while Perpetual PoE maintains power during switch reboots or upgrades. Together, they ensure continuous, reliable operation of Powered devices (PD) in mission‑critical environments. T(P)GR-3208T-WEB supports a maximum PoE budget of 80W and offers advanced PoE management features such as auto-detection and scheduling. The PoE detection automatically identifies unresponsive the PD and promptly restarts them. Additionally, PoE scheduling enables preset power feeding based on routine timetables. Each PoE port can be individually enabled or disabled and provides real-time data on voltage, current, power (W), and temperature. Galvanic isolation between the power input and Ethernet power system enhances safety. Extra PoE galvanic isolation on 802.3at/af ports insulates the power input from PoE Ethernet ports, preventing damage from cabling and grounding incidents to the Ethernet switch.

Sleep Mode & efficient PoE timer under Ignition-Off State on IGN model
The PoE-IGN model supports network operation for up to 60 minutes before entering Sleep Mode (0.048W), preventing unnecessary reboots when power is restored. It also includes a configurable PoE timer, with a default delay of 10 minutes after ignition-off. The Ignition timer allows flexible configuration of both individual PoE port shutdown delays and system shutdown (Sleep Mode), ranging from 30 seconds to 60 minutes (default: 60 minutes). This design eliminates the need for additional relay wiring and enables remote PoE timer configuration anytime, from anywhere.

mDNS (Multicast DNS) and DNS server/client feature and MQTT-role of Publisher or Broker, ITxPT Inventory service, X status
T(P)GR-3208T-WEB supports mDNS (Multicast DNS), enabling hosts within the LAN to discover and communicate with each other following DNS protocol, without the need for a traditional DNS server. The switch also functions as an MQTT Publisher or Broker, sending data to the broker which then distributes the “payload” to subscribers efficiently using a lightweight protocol. In addition, the switch supports ITxPT Inventory service, X status, DNS-SD, and MQTT protocols for comprehensive remote monitoring of Ethernet switch status.

Reliable eMMC for better power efficiency and reliability
T(P)GR-3208T-WEB utilizes eMMC for firmware storage, enhancing product reliability and effectively extending its lifespan under frequent power on/off conditions.

Comprehensive Network Protection Against DDoS and Layer 2 Threats
Lantech OS2Pro generation integrates advanced security mechanisms to safeguard both switches and networks. Key features include DDoS attack mitigation, 802.1X port-based authentication, Dynamic ARP Inspection (DAI), IP Source Guard, and Port Security, providing multi-layer protection against spoofing, unauthorized access, and traffic floods. These security capabilities ensure stable, resilient network operation.

Lantech OS2 PRO Generation with L2 management and routing protocols incl. OSPF and RIP V1&V2
T(P)GR-3208T-WEB developed on the Lantech OS2 Pro generation, is equipped with comprehensive Layer 2 management and routing protocols, including inter-VLAN routing, OSPF, and RIP v1/v2. Designed for versatile vehicle applications, the generation further supports advanced networking functions such as NAT, port forwarding, multiple static IP addresses, DHCP (server/option/client/port-based), VLAN, DHCP over VLAN, IGMP, RSTP/G.8032 enhanced ring recovery, LACP, and more.

Open RESTful API for Seamless Integration and High-Performance Network Management
The switch features a lightweight and efficient Open RESTful API designed for seamless integration with centralized network management software. Using standard HTTP methods (GET, PUT, POST, DELETE) and JSON data structures, the API enables real-time access to configuration and operational data. By leveraging modern web technologies, the switch minimizes CPU overhead typically associated with traditional SNMP polling, delivering faster response times, reduced system load, and improved scalability for high-performance network environments.

User-friendly GUI, Auto topology drawing, Editable configuration text file, CPU watchdog, Snapshot switch information for trouble-shooting analysis
T(P)GR-3208T-WEB offers a user-friendly UI complemented by innovative auto topology drawing and topology demo features, simplifying network management. Configuration files can be exported as editable text files, facilitating easy modification and mass deployment. Its built-in watchdog function automatically reboots the switch if the CPU becomes unresponsive. Additionally, the unique Snapshot feature enables data collection—including port statistics, system core info, configurations, and event logs—either on-demand or scheduled, helping quickly identify and resolve network issues.

OPTIONAL FEATURES
