- Ports 1-4 (RJ45): 2.5G Base-T Ethernet ports, compatible with 10/100/1000/2500Mbps.
- Ports 5-6 (SFP+): 10G SFP+ ports, compatible with 1G/2.5G/10G SFP/SFP+ modules (modules not included).
- Indicadores LED:
- Link/Act (Yellow): On for link, blinking for data activity.
- 2.5G Link (Green): On when connected at 2.5Gbps.
- Potência: Indica o status de energia.
- Entrada de energia: 12V DC power jack.
3. Configuração e instalação
The NICGIGA 6 Port 2.5G Unmanaged Ethernet Switch is designed for simple plug-and-play installation. No software configuration is required.
3.1 Conectando o Interruptor
- Conecte a energia: Plug the provided 12V DC power adapter into the switch's power input port and then into a standard electrical outlet. The PWR LED should illuminate.
- Conectar dispositivos:
- For RJ45 devices (e.g., computers, NAS, WiFi 6 APs): Connect standard Ethernet cables from your devices to any of the 2.5G RJ45 ports (1-4) on the switch.
- For SFP+ devices (e.g., servers, other switches): Insert compatible SFP/SFP+ modules (not included) into the 10G SFP+ ports (5-6) and connect appropriate fiber optic or DAC cables to your devices.
- Verifique a conexão: Once devices are connected, observe the Link/Act and 2.5G Link LEDs on the front panel. A solid yellow Link/Act LED indicates a successful link, and a blinking yellow LED indicates data activity. A solid green 2.5G Link LED indicates a 2.5Gbps connection.
