6. Bedienungsanleitung
The Cudy GS105D operates automatically once powered on and connected. It is an unmanaged switch, meaning no user configuration is required. Key operational features include:
- Automatische Verhandlung: Each port automatically detects the link speed (10/100/1000Mbps) of a connected network device and intelligently adjusts for compatibility and optimal performance.
- Auto MDI/MDIX: Eliminates the need for crossover cables, simplifying network connections. You can use either straight-through or crossover Ethernet cables for any port.
- Lüfterloses Design: Ensures silent operation, ideal for home or office environments where noise reduction is desired.
- Cudy Green Technology: The switch automatically adjusts power consumption based on the link status and cable length, saving energy.
