### 4. Functionality

The TXPS-1080-M12-BP2-24V functions as an unmanaged Ethernet switch with integrated Power over Ethernet (PoE) capability. It automatically detects connected devices and negotiates link speed (10/100/500 Mbps) without requiring manual configuration.

Power over Ethernet Function:
Each port acts as a Power Sourcing Equipment (P.S.E.), supplying DC power to connected Powered Devices (PDs) such as IP cameras, wireless access points, or VoIP phones. This eliminates the need for separate power wiring, simplifying installation in constrained environments like train carriages or vehicles.

Bypass Functionality:
The BP2 model includes a hardware-based bypass circuit on the last two ports. In the event of power loss or switch failure, these ports automatically connect directly, maintaining network continuity and preventing communication breakdowns in daisy-chain or ring topologies.

Use Cases and Applications:
- Railway and rolling stock communication systems
- Onboard IP surveillance and passenger information systems
- Vehicle and bus network infrastructure
- Industrial automation and control networks
- Transportation monitoring and signaling systems

Compatibility:
Compatible with standard Ethernet devices supporting IEEE 802.3/802.3u/802.3at. Works seamlessly with ORing’s Open-Vision management utility for network monitoring (though unmanaged, it can be detected and monitored).
