4. Opsætning
The NICGIGA 24 Port 2.5Gb Ethernet Switch is designed for simple plug-and-play operation, requiring no software installation or complex configuration.
4.1 Desktop-installation
- Place the switch on a stable, flat surface, ensuring adequate ventilation around the device.
- Tilslut strømadapteren til switchens strømindgang og derefter til en stikkontakt.
- Connect your network devices (e.g., computers, NAS, Wi-Fi 6 APs, routers) to any of the 24 RJ45 ports using standard Ethernet cables. The switch will automatically detect the link speed.

5. Betjeningsvejledning
Once the switch is powered on and devices are connected, it operates automatically.
- Auto-forhandling: Each port automatically detects the speed (100Mbps, 1Gbps, or 2.5Gbps) and duplex mode (half/full) of the connected device and adjusts accordingly. This ensures optimal performance and compatibility across various network devices.
- Ikke-blokerende arkitektur: The switch provides full wire-speed forwarding on all ports simultaneously, ensuring maximum throughput for all connected devices without bottlenecks.
- Uadministreret operation: No configuration or software is required. Simply connect your devices, and the switch will manage data traffic efficiently.

6. Vedligeholdelse
The NICGIGA 24 Port 2.5Gb Ethernet Switch is designed for minimal maintenance.
- Rensning: Brug en blød, tør klud til at rengøre ydersiden af kontakten. Brug ikke flydende rengøringsmidler eller rengøringsmidler på sprayform.
- Ventilation: Ensure that the ventilation openings are not blocked to allow for proper airflow and heat dissipation. The fanless design relies on natural convection.
- Miljø: Brug kontakten inden for de specificerede miljøforhold (temperatur, fugtighed) for at sikre optimal ydeevne og levetid.
7. Fejlfinding
If you encounter issues with your NICGIGA 24 Port 2.5Gb Ethernet Switch, refer to the following common troubleshooting steps:
- Ingen strøm:
- Sørg for, at strømadapteren er korrekt tilsluttet både afbryderen og en fungerende stikkontakt.
- Kontroller, at stikkontakten fungerer ved at tilslutte en anden enhed.
- Check the Power LED on the switch; it should be solid green when powered on.
- Ingen link/aktivitet på en port:
- Kontroller, at Ethernet-kablet er korrekt tilsluttet til både switchporten og den tilsluttede enhed.
- Sørg for, at den tilsluttede enhed er tændt, og at dens netværksadapter fungerer korrekt.
- Try a different Ethernet cable to rule out cable issues.
- Test med en anden port på switchen.
- Check the LED indicator for the specific port; if it's off, there's no link.
- Langsom netværkshastighed:
- Ensure all connected devices and network adapters support 2.5Gbps speeds for optimal performance. The switch will auto-negotiate to the highest common speed.
- Use Cat5e or higher-rated Ethernet cables for 2.5Gbps connections.
- Check for excessive network traffic or bottlenecks on other network devices.
- Intermitterende forbindelse:
- Inspect Ethernet cables for damage.
- Ensure the switch is placed in a well-ventilated area to prevent overheating, although it has a fanless design.
- Kontrollér for potentiel elektromagnetisk interferens fra andre elektroniske enheder.
