5. Instrucciones de funcionamiento
5.1 Indicadores LED
The front panel features several LED indicators to monitor the status of the switch and its ports.
Figura 3: detallada view of LED Indicators and Loop Detection Switch.
| Nombre del LED | Estado | Descripción |
|---|---|---|
| FUERZA | On | El dispositivo está encendido. |
| ENLACE / ACTUAR (por puerto) | On | A network device is connected and a link is established. |
| Brillante | Se están transmitiendo o recibiendo datos a través del puerto. | |
| 1000/100/10M (por puerto) | Verde | Port is operating at 1000 Mbps (Gigabit Ethernet). |
| Naranja | Port is operating at 100 Mbps (Fast Ethernet). | |
| Apagado | 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).
- EN: 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. Mantenimiento
6.1 Limpieza del dispositivo
Para mantener un rendimiento óptimo, limpie periódicamente el exterior del interruptor.
- Desconecte el cable de alimentación antes de limpiar.
- Utilice un paño suave y seco para limpiar la superficie.
- Do not use liquid cleaners, aerosols, or solvents, as these may damage the casing o componentes internos.
6.2 Consideraciones ambientales
Ensure the device is operated within its specified environmental conditions:
- Temperatura: 0 °C a 40 °C (32 °F a 104 °F)
- Humedad: 10% a 85% (sin condensación)
7. Solución de problemas
If you encounter issues with your BUFFALO Giga Switching Hub, refer to the following common problems and solutions.
7.1 Sin energía
- Síntoma: El LED de ENCENDIDO está apagado.
- Solución: Compruebe que el cable de alimentación esté bien conectado tanto al dispositivo como a la toma de corriente. Asegúrese de que la toma de corriente funcione.
7.2 No Link or Slow Speed on a Port
- Síntoma: 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).
- Solución:
- Verifique que el cable Ethernet esté conectado de forma segura en ambos extremos.
- Try a different Ethernet cable. Ensure it is a Category 5e or higher cable for Gigabit speeds.
- Conecte el dispositivo a un puerto diferente en el conmutador.
- 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
- Síntoma: The LOOP DETECT LED is illuminated, and network performance is degraded or unstable.
- Solución:
- 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.
