4. Nastavitev
4.1 Fizična namestitev
The LSW3-GT-24NSR can be installed on a desktop or mounted in a 19-inch equipment rack.
Postavitev na namizje:
- Attach the included rubber feet to the bottom of the unit to prevent slipping and provide stability.
- Place the unit on a flat, stable surface with adequate ventilation.
Montaža na stojalo:
- 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 Priključitev omrežnih kablov
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. Navodila za uporabo
5.1 LED indikatorji
The front panel features several LED indicators to monitor the status of the switch and its ports.

Slika 3: Podrobno view of LED Indicators and Loop Detection Switch.
| Ime LED | Stanje | Opis |
|---|---|---|
| MOČ | On | Naprava je vklopljena. |
| POVEZAVA / AKT (na vrata) | On | A network device is connected and a link is established. |
| Utripa | Podatki se prenašajo ali prejemajo prek vrat. | |
| 1000/100/10M (na vrata) | zelena | Port is operating at 1000 Mbps (Gigabit Ethernet). |
| Oranžna | Port is operating at 100 Mbps (Fast Ethernet). | |
| Izključeno | Port is operating at 10 Mbps (Ethernet). | |
| LOOP DETECT | On | A network loop has been detected. |
5.2 Funkcija zaznavanja zanke
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).
- VKLOPLJENO: 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.
- IZKLOPLJENO: Loop detection is disabled.
It is recommended to keep the loop detection function ON for network stability.
6. Vzdrževanje
6.1 Čiščenje naprave
To maintain optimal performance, periodically clean the exterior of the switch.
- Pred čiščenjem izključite napajalni kabel.
- Za brisanje površine uporabite mehko, suho krpo.
- Do not use liquid cleaners, aerosols, or solvents, as these may damage the casing ali notranjih komponent.
6.2 Okoljski vidiki
Ensure the device is operated within its specified environmental conditions:
- Temperatura: 0 °C do 40 °C (32 °F do 104 °F)
- Vlažnost: 10 % do 85 % (brez kondenzacije)
7. Odpravljanje težav
If you encounter issues with your BUFFALO Giga Switching Hub, refer to the following common problems and solutions.
7.1 Brez napajanja
- Simptom: LED POWER ne sveti.
- rešitev: 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
- Simptom: 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).
- rešitev:
- Preverite, ali je ethernetni kabel varno priključen na obeh koncih.
- Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
- Napravo priključite na druga vrata na stikalu.
- 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
- Simptom: The LOOP DETECT LED is illuminated, and network performance is degraded or unstable.
- rešitev:
- 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.
