• КҮЙҮК: 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.
• ӨЧҮК: Loop detection is disabled.

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

6. Техникалык тейлөө

6.1 Аппаратты тазалоо

Оптималдуу иштөөсүн сактоо үчүн, өчүргүчтүн сыртын мезгил-мезгили менен тазалап туруңуз.

• Тазалоодон мурун электр кабелин сууруп алыңыз.
• Бетти сүртүү үчүн жумшак, кургак чүпүрөктү колдонуңуз.
• Do not use liquid cleaners, aerosols, or solvents, as these may damage the casing же ички компоненттер.

6.2 Айлана-чөйрөнү коргоо

Ensure the device is operated within its specified environmental conditions:

• Температура: 0°Cден 40°Cге чейин (32°F—104°F)
• Нымдуулук: 10% - 85% (конденсацияланбаган)

7. Кыйынчылыктарды

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

7.1 Күч жок

• Белги: POWER LED өчүк.
• Чечим: 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

• Белги: 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).
• Чечим:
  • Ethernet кабелинин эки учунан тең бекем туташтырылганын текшериңиз.
  • Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
  • Түзмөктү коммутатордогу башка портко туташтырыңыз.
  • 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

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