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).

• НА: 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.
• ВАН: Loop detection is disabled.

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

6. Одржавање

6.1 Чишћење уређаја

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

• Disconnect the power cable before cleaning.
• Користите меку, суву крпу да обришете површину.
• Do not use liquid cleaners, aerosols, or solvents, as these may damage the casinг или унутрашње компоненте.

6.2 Разматрања животне средине

Ensure the device is operated within its specified environmental conditions:

• температура: 0°Ц до 40°Ц (32°Ф до 104°Ф)
• Влажност: 10% до 85% (без кондензације)

КСНУМКС. Решавање проблема

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

7.1 Нема напајања

• Симптом: ЛЕД лампица ПОВЕР је искључена.
• решење: 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

• Симптом: 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).
• решење:
  • Проверите да ли је Етернет кабл безбедно повезан на оба краја.
  • Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
  • Повежите уређај са другим портом на прекидачу.
  • 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

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