3. Pokyny k nastavení
The LIANGUO 2.5G PoE Switch is designed for plug-and-play operation, requiring no complex configuration.
3.1 Fyzická instalace
- Rozbalte přepínač: Opatrně vyjměte spínač z obalu.
- Umístění: Place the switch on a stable, flat surface or mount it in a suitable rack. Ensure adequate ventilation around the device.
- Připojte napájení: Connect the provided power cord to the switch's AC input port (100-240V, 50/60Hz) and then to a power outlet.
- Základy: For enhanced safety, connect a grounding wire to the grounding screw on the back of the switch.
3.2 Síťová připojení
The switch supports MDI/MDIX automatic flipping and rate auto-negotiation, simplifying cable connections.
- Připojení síťových zařízení: Connect your network devices (e.g., WiFi 6e APs, IP phones, PoE cameras, computers, NAS servers) to the 8x 100/1000/2500M PoE ports using Cat5e or above network cables.
- Připojení k odchozímu spojení: For high-speed uplink to a router or core network, insert a compatible SFP Module/DAC/AOC into the 1x 10G SFP+ slot. This port supports 10M/100M/1G/2.5G/10G speeds.
- Napájení přes Ethernet (PoE): The PoE ports (1-8) automatically detect and supply power to compatible PoE-powered devices (PDs) according to IEEE802.3af (15.4W) and IEEE802.3at (30W) standards.

4. Návod k obsluze
4.1 Zapnutí
Once the power cord is connected, the switch will power on automatically. The PWR indicator light will illuminate.
4.2 Port Indicators
Each Ethernet port has indicator lights to show its status:
- Odkaz/Akce: Indicates a network connection and activity.
- Rychlost: Indicates the connection speed (e.g., Orange for 10/100/1000M, Green for 2.5G).
4.3 PoE Priority
The switch supports PoE priority on ports 1 through 8. By default, ports 1-8 are configured to prioritize power delivery. This ensures critical devices receive power first in scenarios where total power demand exceeds the switch's maximum PoE budget (90W).

5.4 Čištění
Pravidelně čistěte vnější povrch spínače měkkým, suchým hadříkem. Nepoužívejte tekuté ani aerosolové čisticí prostředky.
6. Řešení problémů
If you encounter issues with your LIANGUO 2.5G PoE Switch, consider the following basic troubleshooting steps:
- Bez napájení: Ensure the power cord is securely connected to both the switch and a working power outlet. Check if the PWR indicator is lit.
- Žádný odkaz/aktivita: Verify that network cables are properly connected to both the switch and the connected device. Ensure the connected device is powered on and functioning correctly. Try a different network cable.
- Zařízení PoE se nezapíná: Confirm that the connected device is a PoE-powered device (PD) and compatible with IEEE802.3af/at standards. Check the total PoE power budget (max 90W) to ensure it's not exceeded.
- Pomalá rychlost připojení: Ensure you are using Cat5e or higher-grade network cables for 2.5Gbps connections. Check the speed indicator lights on the ports.
For persistent issues, refer to the detailed specifications or contact technical support.
