5.2 Loop Detection Function

The LSW3-GT-24NSR features a hardware switch for enabling or disabling the loop detection function. This function helps prevent network instability caused by accidental network loops.

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

• AR: 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.
• AS: Loop detection is disabled.

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

6. Cothabháil

6.1 An Gléas a Ghlanadh

To maintain optimal performance, periodically clean the exterior of the switch.

• Dícheangail an cábla cumhachta roimh ghlanadh.
• Bain úsáid as éadach bog tirim chun an dromchla a ghlanadh.
• Do not use liquid cleaners, aerosols, or solvents, as these may damage the casing nó comhpháirteanna inmheánacha.

6.2 Cúrsaí Timpeallachta

Ensure the device is operated within its specified environmental conditions:

• Teocht: 0°C go 40°C (32°F go 104°F)
• Taise: 10% go 85% (neamh-chomhdhlúthaithe)

7. Fabhtcheartú

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

7.1 Gan Cumhacht

• Airí: Tá an POWER LED múchta.
• Réiteach: 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

• Airí: 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).
• Réiteach:
  • Verify the Ethernet cable is securely connected at both ends.
  • Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
  • Ceangail an gléas le port difriúil ar an lasc.
  • 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

• Airí: The LOOP DETECT LED is illuminated, and network performance is degraded or unstable.
• Réiteach:
  • 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.
