LED indikátory:
- LED napájení: Indikuje stav napájení spínače.
- 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. Nastavení a instalace
Follow these steps to set up your KuWFi PoE Ethernet Switch:
- Umístění: Place the switch on a stable, flat surface or mount it in a suitable location. Ensure adequate ventilation around the device.
- Připojení napájení: 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.
- Připojení k odchozímu spojení: 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.
- Připojení zařízení 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. Ovládání přepínače
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.
Funkce PoE:
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.
Gigabitová rychlost:
All ports support Gigabit Ethernet (10/100/1000 Mbps) for high-speed data transfer, ensuring efficient performance for connected devices.
Aplikační scénáře:

6. Údržba
To ensure optimal performance and longevity of your KuWFi PoE Ethernet Switch, follow these maintenance guidelines:
- Čištění: Pravidelně čistěte vnější povrch spínače měkkým, suchým hadříkem. Nepoužívejte tekuté ani aerosolové čisticí prostředky.
- Větrání: Ujistěte se, že ventilační otvory nejsou zablokované. Správné proudění vzduchu zabraňuje přehřátí.
- Prostředí: Operate the switch within its specified temperature and humidity ranges. Avoid exposure to direct sunlight, excessive heat, or moisture.
- Správa kabelů: Udržujte síťové kabely uspořádané a bez zauzlení nebo nadměrného ohýbání, abyste zabránili degradaci signálu.
7. Řešení problémů
If you encounter issues with your KuWFi PoE Ethernet Switch, refer to the following common troubleshooting steps:
- Bez napájení:
- Zkontrolujte, zda je napájecí kabel bezpečně připojen k vypínači i k elektrické zásuvce.
- Ověřte, zda je elektrická zásuvka funkční.
- Ensure the Power LED on the switch is illuminated.
- Žádné síťové připojení:
- 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.
- Zařízení PoE se nezapíná:
- 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.
- Pomalá rychlost sítě:
- Verify that all connected devices and cables support Gigabit Ethernet (1000 Mbps).
- Check for network congestion or issues with the uplink connection.
