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).

• ເປີດ: 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.
• ປິດ: Loop detection is disabled.

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

6. ບໍາລຸງຮັກສາ

6.1 ການທໍາຄວາມສະອາດອຸປະກອນ

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

• ຖອດສາຍໄຟອອກກ່ອນທຳຄວາມສະອາດ.
• ໃຊ້ຜ້າປຽກອ່ອນໆເຊັດພື້ນຜິວ.
• Do not use liquid cleaners, aerosols, or solvents, as these may damage the casing ຫຼືອົງປະກອບພາຍໃນ.

6.2 ການພິຈາລະນາດ້ານສິ່ງແວດລ້ອມ

Ensure the device is operated within its specified environmental conditions:

• ອຸນຫະພູມ: 0°C ຫາ 40°C (32°F ຫາ 104°F)
• ຄວາມຊຸ່ມຊື່ນ: 10% ຫາ 85% (ບໍ່ condensing)

7. ການແກ້ໄຂບັນຫາ

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

7.1 ບໍ່ມີພະລັງງານ

• ອາການ: ໄຟ LED ປິດ.
• ການແກ້ໄຂ: 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

• ອາການ: 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).
• ການແກ້ໄຂ:
  • ກວດສອບວ່າສາຍ Ethernet ໄດ້ເຊື່ອມຕໍ່ກັນຢ່າງແໜ້ນໜາຢູ່ທັງສອງສົ້ນ.
  • Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
  • ເຊື່ອມຕໍ່ອຸປະກອນກັບພອດອື່ນໃນສະວິດ.
  • 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

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