### 4. Functionality

The TPS-141TX-M12-MV functions as an unmanaged Ethernet switch, automatically forwarding Ethernet frames between connected devices without requiring configuration. It supports auto-negotiation and auto-MDI/MDI-X, allowing seamless connection to a variety of Ethernet devices such as IP cameras, wireless access points, and controllers.

Use Cases and Applications:
- Railway and rolling stock Ethernet networks (EN50155 compliant)
- Vehicle-based communication systems
- Industrial automation and control systems
- IP surveillance and security systems
- Transportation and fleet management networks
- Harsh outdoor or mobile environments requiring vibration-resistant connectivity

Compatibility:
- Compatible with standard 10/100Base-T(X) Ethernet devices
- Supports PoE-powered devices compliant with IEEE 802.3af/at standards
- Integrates easily into existing unmanaged or managed network infrastructures

Operation Principle:
The switch uses store-and-forward packet processing to ensure error-free data transmission. Each port automatically detects link speed and duplex mode, while flow control prevents packet loss under heavy traffic. PoE ports deliver both data and power over the same Ethernet cable, simplifying installation and reducing wiring complexity.
