4. Enstalasyon
4.1 Enstalasyon Fizik
The LSW3-GT-24NSR can be installed on a desktop or mounted in a 19-inch equipment rack.
Plasman Desktop:
- Attach the included rubber feet to the bottom of the unit to prevent slipping and provide stability.
- Mete aparèy la sou yon sifas plat, ki estab e ki gen ase vantilasyon.
Montaj etajè:
- Attach the rack mount brackets to the sides of the unit using the provided screws.
- Secure the unit into a standard 19-inch equipment rack using appropriate rack screws (not included).
4.2 Konekte kab rezo yo
Connect your network devices (computers, servers, other switches) to any of the 24 RJ-45 ports on the front panel using standard Ethernet cables (Category 5e or higher recommended for Gigabit speeds).

5. Operasyon Enstriksyon
5.1 Endikatè ki ap dirije
The front panel features several LED indicators to monitor the status of the switch and its ports.

Figi 3: Detaye view of LED Indicators and Loop Detection Switch.
| Non ki ap dirije | Estati | Deskripsyon |
|---|---|---|
| POUVWA | On | Aparèy la limen. |
| LINK / ACT (pa pò) | On | A network device is connected and a link is established. |
| Flache | Done yo ap transmèt oswa resevwa atravè pò a. | |
| 1000/100/10M (pa pò) | Vèt | Port is operating at 1000 Mbps (Gigabit Ethernet). |
| Orange | Port is operating at 100 Mbps (Fast Ethernet). | |
| Off | 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).
- SOU: 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.
- OFF: Loop detection is disabled.
It is recommended to keep the loop detection function ON for network stability.
6. Antretyen
6.1 Netwaye Aparèy la
Pou kenbe pèfòmans optimal, netwaye deyò switch la detanzantan.
- Disconnect the power cable before cleaning.
- Sèvi ak yon twal mou, sèk pou siye sifas la.
- Do not use liquid cleaners, aerosols, or solvents, as these may damage the casing oswa konpozan entèn yo.
6.2 Konsiderasyon Anviwònman
Ensure the device is operated within its specified environmental conditions:
- Tanperati: 0°C a 40°C (32°F a 104°F)
- Imidite: 10% a 85% (ki pa kondanse)
NAN. Depanaj
If you encounter issues with your BUFFALO Giga Switching Hub, refer to the following common problems and solutions.
7.1 Pa gen pouvwa
- sentòm: POWER LED la etenn.
- Solisyon: 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
- sentòm: 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).
- Solisyon:
- Verifye ke kab Ethernet la byen konekte nan tou de bout yo.
- Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
- Konekte aparèy la nan yon lòt pò sou switch la.
- 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
- sentòm: The LOOP DETECT LED is illuminated, and network performance is degraded or unstable.
- Solisyon:
- 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.
