### 4. Functionality

The TGPS-1080-M12-24V functions as an unmanaged Ethernet switch, automatically detecting and forwarding Ethernet frames between connected devices. Each of its eight M12 ports supports auto-negotiation for 10/100/1000 Mbps speeds and full/half-duplex operation.

Power over Ethernet (PoE):
Each port acts as a Power Sourcing Equipment (PSE), delivering DC power to connected Powered Devices (PDs) such as IP cameras, wireless access points, or VoIP phones. This eliminates the need for separate power cabling, simplifying installation in mobile or remote environments.

Redundant Power Inputs:
The switch features dual DC power inputs. If the primary power source fails, the secondary input automatically takes over, ensuring continuous operation.

Use Cases and Applications:
- Railway and rolling stock communication systems
- Onboard IP surveillance and passenger information systems
- Industrial automation and control networks
- Vehicle-based networking (buses, trams, service vehicles)
- Harsh-environment Ethernet connectivity

Compatibility:
Compliant with IEEE Ethernet and PoE standards, compatible with all standard Ethernet devices and PoE-powered equipment.
