Figure 4: Loop Detection Switch (ON/OFF).

  • SOPRA: Loop detection is active. If a loop is detected, the corresponding port will be automatically shut down to prevent network broadcast storms, and the LOOP DETECT LED will illuminate.
  • OFF: Loop detection is disabled.

It is recommended to keep the loop detection function ON for network stability.

6. Manutenzione

6.1 Pulizia del dispositivo

Per mantenere prestazioni ottimali, pulire periodicamente la parte esterna dell'interruttore.

  • Scollegare il cavo di alimentazione prima della pulizia.
  • Utilizzare un panno morbido e asciutto per pulire la superficie.
  • Do not use liquid cleaners, aerosols, or solvents, as these may damage the casing o componenti interni.

6.2 Considerazioni ambientali

Ensure the device is operated within its specified environmental conditions:

  • Temperatura: da 0°C a 40°C (da 32°F a 104°F)
  • Umidità: Dal 10% all'85% (senza condensa)

7. Risoluzione Dei Problemi

If you encounter issues with your BUFFALO Giga Switching Hub, refer to the following common problems and solutions.

7.1 Nessun potere

  • sintomo: Il LED POWER è spento.
  • Soluzione: Check if the power cable is securely connected to both the device and the power outlet. Ensure the power outlet is functional.

7.2 No Link or Slow Speed on a Port

  • sintomo: The LINK/ACT LED for a connected port is off, or the 1000/100/10M LED indicates a lower speed than expected (e.g., 100M instead of 1000M).
  • Soluzione:
    • Verificare che il cavo Ethernet sia collegato saldamente a entrambe le estremità.
    • Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
    • Collegare il dispositivo a una porta diversa dello switch.
    • Check the network adapter settings on the connected device (computer, server) to ensure it is configured for auto-negotiation or the correct speed.

7.3 Network Instability / LOOP DETECT LED is On

  • sintomo: The LOOP DETECT LED is illuminated, and network performance is degraded or unstable.
  • Soluzione:
    • A network loop has been detected. This typically occurs when two ports on the same switch (or different switches) are connected to each other, creating an infinite data path.
    • Carefully inspect your network cabling to identify and remove any redundant connections that form a loop.
    • If the loop detection switch is ON, the affected port will be automatically shut down. Once the loop is resolved, the port should resume normal operation.
