5.2 firmwareopdateringer
As an unmanaged switch, the S25-0402T typically does not require user-initiated firmware updates. Any necessary updates are handled internally by the manufacturer.
6. Fejlfinding
If you encounter issues with your NICGIGA S25-0402T switch, refer to the following common troubleshooting steps:
6.1 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. If it is off, the device is not receiving power.
6.2 No Link Light / No Network Connectivity
- Kontroller, at Ethernet-kablet er korrekt tilsluttet både switchporten og den tilsluttede enhed.
- Prøv et andet Ethernet-kabel for at udelukke et defekt kabel.
- Tilslut enheden til en anden port på switchen.
- Ensure the connected device (e.g., computer, router) is powered on and its network adapter is enabled.
- Check the LED indicators for the specific port. If no link light is present, there is no active connection.
- Restart the switch by unplugging and re-plugging the power adapter.
6.3 Langsom netværkshastighed
- Ensure you are using appropriate Ethernet cable types for the desired speed (e.g., Cat6a or Cat7 for 10Gbps connections).
- Verify that the network adapter in your connected device supports the desired speed (e.g., a 2.5Gbps or 10Gbps NIC).
- Check the port LED indicators to confirm the negotiated link speed.
- Ensure there are no other network bottlenecks (e.g., slow router, internet service provider limitations).
