3.1. Ports i indicadors
- Entrada d'alimentació de CC de 12 V i 1.5 A: Connecteu l'adaptador d'alimentació inclòs aquí.
- 8x 2.5G RJ45 Ports (1-8): These ports support 100/1000/2500Mbps speeds with auto-negotiation.
- 2x 10G SFP+ Ports (9-10): These ports support 1G/2.5G/10G speeds for high-bandwidth uplink connections. SFP+ modules are not included.
- Indicadors LED:
- RJ45 Ports (1-8) Yellow Light: On indicates 100/1000/2500Mbps link. Blinking indicates data transfer. Off means the link is unavailable.
- RJ45 Ports (1-8) Green Light: On indicates a 2.5G link. Off means the link is unavailable.
- SFP+ Ports (9-10) Link/Act LED: On indicates a stable link. Blinking indicates data transfer.
- LED d'alimentació: On indicates the device is powered on.

The 10G SFP+ uplink ports support adaptive 1G/2.5G/10G optical fiber modules (modules not included).
4. Instruccions de configuració
The NICGIGA switch is designed for simple plug-and-play installation.
- Connexió d'alimentació: Connect the provided power adapter to the DC 12V 1.5A power input port on the switch and then plug it into a standard electrical outlet. The Power LED should illuminate.
- Network Device Connection (RJ45): Connect your network devices (e.g., computers, NAS, WiFi 6 APs, routers) to the 2.5G RJ45 ports (1-8) using standard Ethernet cables. The switch will automatically detect the link speed (100Mbps, 1Gbps, or 2.5Gbps) and configure itself. The corresponding LED indicators will light up.
- Uplink Connection (SFP+): For high-speed uplink to a core network or server, insert a compatible 1G/2.5G/10G SFP+ module (not included) into one of the SFP+ ports (9-10). Then, connect an appropriate fiber optic cable or DAC cable to the SFP+ module and your target device. The Link/Act LED for the SFP+ port will illuminate upon successful connection.

The switch features a compact design, fanless operation, and supports plug-and-play installation with a 60Gbps switching capacity.
4.1. Muntatge a la paret
The switch includes two wall-hanging holes on the bottom for flexible placement in various environments.

The switch can be conveniently mounted on a wall using the integrated hanging holes.
5. Instruccions de funcionament
As an unmanaged switch, the NICGIGA S25-0802 operates automatically once connected. No software configuration is required.
- Automatic Negotiation: All RJ45 ports automatically detect the speed of connected devices (100Mbps, 1Gbps, 2.5Gbps) and adjust accordingly. The SFP+ ports support 1G, 2.5G, and 10G.
- Non-Blocking Data Forwarding: The switch provides full wire-speed forwarding on all ports simultaneously, ensuring maximum throughput for all connected devices.
- Disseny sense ventilador: The fanless operation ensures silent performance, making it suitable for noise-sensitive environments like home offices.

The switch facilitates building a high-speed 2.5G network for various devices throughout a home or office.
6. Manteniment
To ensure optimal performance and longevity of your NICGIGA switch, follow these maintenance guidelines:
- Col·locació: Place the switch in a well-ventilated area, away from direct sunlight, heat sources, and excessive moisture. Ensure adequate airflow around the device.
- Neteja: Feu servir un drap suau i sec per netejar l'exterior de l'interruptor. No utilitzeu netejadors líquids ni en aerosol.
- Gestió de cables: Ensure all network cables are properly routed and secured to prevent accidental disconnections or damage.
- Font d'alimentació: Use only the provided power adapter. Disconnect the power adapter during electrical storms or when unused for extended periods.
7. Solució De Problemes
Si teniu problemes amb el commutador, consulteu els passos habituals següents per a la resolució de problemes:
- Sense energia:
- Assegureu-vos que l'adaptador de corrent estigui connectat correctament a l'interruptor i a una presa de corrent que funcioni.
- Verifiqueu que la presa de corrent funciona connectant-hi un altre dispositiu.
- No Link Light on an RJ45 Port:
- Check if the Ethernet cable is securely plugged into both the switch port and the connected device.
- Prova un cable Ethernet diferent per descartar una fallada del cable.
- Assegureu-vos que el dispositiu connectat estigui encès i que el seu adaptador de xarxa funcioni correctament.
- Reinicieu el dispositiu connectat.
- No Link Light on an SFP+ Port:
- Ensure the SFP+ module is correctly inserted into the port.
- Verify the fiber optic or DAC cable is securely connected to the SFP+ module and the target device.
- Confirm the SFP+ module and cable are compatible with both the switch and the connected device.
- Check the status of the connected device's SFP+ port.
- Velocitat de xarxa lenta:
- Ensure all connected devices and cables support the desired speed (e.g., 2.5Gbps or 10Gbps). Using older Cat5e cables might limit speeds to 1Gbps or less over longer distances.
- Check for network congestion by disconnecting non-essential devices.
- Verify the network adapter settings on your devices are configured for auto-negotiation or the correct speed.
