Indicadors LED:
- LED d'alimentació: Indica l'estat d'alimentació de l'interruptor.
- PoE Port LEDs (1-8): Indicate data activity and PoE status for each respective port.
- Uplink Port LEDs (9-10): Indicate data activity for the SFP uplink ports.
VLAN Switch:
The switch includes a physical VLAN (Virtual Local Area Network) switch. When enabled, this feature isolates the PoE ports from each other, enhancing security and preventing broadcast storms. The uplink ports remain connected to all PoE ports. When disabled, all ports operate as a standard switch.

4. Configuració i instal·lació
Follow these steps to set up your KuWFi PoE Ethernet Switch:
- Col·locació: Place the switch on a stable, flat surface or mount it in a suitable location. Ensure adequate ventilation around the device.
- Connexió d'alimentació: Connect the provided power line to the power input port on the switch and then to a standard electrical outlet. The Power LED should illuminate.
- Connexió d'enllaç ascendent: Connect your router, NVR, or main network device to one of the 2 Gigabit SFP uplink ports using an appropriate SFP module and fiber cable, or an RJ45 Ethernet cable if using a compatible SFP-to-RJ45 module.
- Connexió de dispositiu PoE: Connect your PoE-compatible devices (e.g., IP cameras, wireless access points) to the 8 PoE RJ45 ports using standard Cat-5 or Cat-6 Ethernet cables. The switch will automatically detect and provide power to these devices.
- VLAN Configuration (Optional): If network segmentation is desired, set the VLAN switch to the 'ON' position. This will isolate the PoE ports from each other while maintaining connectivity to the uplink ports.

5. Funcionament de l'interruptor
Once connected, the KuWFi PoE Ethernet Switch operates automatically. It is a plug-and-play device that requires no complex configuration for basic network extension and PoE functionality.
PoE Functionality:
The switch automatically detects and supplies power to IEEE 802.3af compliant devices connected to its PoE ports. If a non-PoE device is connected, only data transmission will occur, without power being supplied, protecting your equipment.
Velocitat Gigabit:
All ports support Gigabit Ethernet (10/100/1000 Mbps) for high-speed data transfer, ensuring efficient performance for connected devices.
Escenaris d'aplicació:

6. Manteniment
To ensure optimal performance and longevity of your KuWFi PoE Ethernet Switch, follow these maintenance guidelines:
- Neteja: Netegeu regularment l'exterior de l'interruptor amb un drap suau i sec. No utilitzeu netejadors líquids ni en aerosol.
- Ventilació: Assegureu-vos que les obertures de ventilació no estiguin bloquejades. Un flux d'aire adequat evita el sobreescalfament.
- Medi ambient: Operate the switch within its specified temperature and humidity ranges. Avoid exposure to direct sunlight, excessive heat, or moisture.
- Gestió de cables: Mantingueu els cables de xarxa organitzats i lliures de doblegaments o doblegaments excessius per evitar la degradació del senyal.
7. Solució De Problemes
If you encounter issues with your KuWFi PoE Ethernet Switch, refer to the following common troubleshooting steps:
- Sense energia:
- Check if the power cable is securely connected to both the switch and the power outlet.
- Comproveu que la presa de corrent funcioni.
- Assegureu-vos que el LED d'alimentació de l'interruptor estigui encès.
- Sense connexió de xarxa:
- Ensure Ethernet cables are securely connected to both the switch and the connected devices.
- Check the Link/Act LEDs on the switch ports for activity. If no LED is lit, try a different cable or port.
- Verify that the connected devices (router, NVR, IP camera) are powered on and functioning correctly.
- El dispositiu PoE no s'encén:
- Confirm that the connected device is PoE-compatible (IEEE 802.3af standard).
- Try connecting the device to a different PoE port on the switch.
- Ensure the total power consumption of all connected PoE devices does not exceed the switch's power budget.
- Velocitat de xarxa lenta:
- Verify that all connected devices and cables support Gigabit Ethernet (1000 Mbps).
- Check for network congestion or issues with the uplink connection.
