5. Arahan Operasi
5.1 Penunjuk LED
The front panel features several LED indicators to monitor the status of the switch and its ports.

Rajah 3: Terperinci view of LED Indicators and Loop Detection Switch.
| Nama LED | Status | Penerangan |
|---|---|---|
| KUASA | On | Peranti dihidupkan. |
| LINK / AKTA (setiap port) | On | A network device is connected and a link is established. |
| Berkelip | Data sedang dihantar atau diterima melalui port. | |
| 1000/100/10J (setiap port) | hijau | Port is operating at 1000 Mbps (Gigabit Ethernet). |
| Jingga | Port is operating at 100 Mbps (Fast Ethernet). | |
| Mati | Port is operating at 10 Mbps (Ethernet). | |
| LOOP DETECT | On | A network loop has been detected. |
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).
- ON: 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.
- MATI: Loop detection is disabled.
It is recommended to keep the loop detection function ON for network stability.
6. Penyelenggaraan
6.1 Membersihkan Peranti
To maintain optimal performance, periodically clean the exterior of the switch.
- Putuskan sambungan kabel kuasa sebelum membersihkannya.
- Gunakan kain lembut dan kering untuk mengelap permukaan.
- Do not use liquid cleaners, aerosols, or solvents, as these may damage the casing atau komponen dalaman.
6.2 Pertimbangan Alam Sekitar
Ensure the device is operated within its specified environmental conditions:
- Suhu: 0°C hingga 40°C (32°F hingga 104°F)
- Kelembapan: 10% hingga 85% (tidak pemeluwapan)
7. Penyelesaian masalah
If you encounter issues with your BUFFALO Giga Switching Hub, refer to the following common problems and solutions.
7.1 Tiada Kuasa
- Gejala: LED POWER dimatikan.
- Penyelesaian: 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
- Gejala: 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).
- Penyelesaian:
- Sahkan kabel Ethernet disambungkan dengan selamat di kedua-dua hujungnya.
- Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
- Sambungkan peranti ke port lain pada suis.
- 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
- Gejala: The LOOP DETECT LED is illuminated, and network performance is degraded or unstable.
- Penyelesaian:
- 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.
