3. Istruzioni per l'installazione
Follow these steps to set up your Real HD 5 Port 2.5Gb Ethernet Switch.
3.1 Posizionamento fisico
- Place the switch on a stable, flat surface such as a desktop, or mount it to a wall using appropriate hardware (not included).
- Ensure adequate ventilation around the device. Although fanless, proper airflow helps maintain optimal operating temperature.
- Keep the switch away from strong electromagnetic fields, direct sunlight, and sources of excessive heat or moisture.
3.2 Collegamento dello switch

Figura 3.1: Posteriore view of the switch showing power input and port layout.
- Connetti alimentazione: Insert the power adapter into the DC 12V port on the switch and plug the other end into a standard electrical outlet. The Power (PWR) LED indicator on the front panel will illuminate.
- Connect Network Devices (RJ45 Ports): Use CAT6 or higher-level pure copper Ethernet cables to connect your network devices (e.g., computers, routers, NAS, WiFi 6 APs) to any of the five 2.5G RJ45 ports (labeled 1-5). For optimal 2.5Gbps speeds, ensure all connected devices and cables support 2.5Gbps.
- Connect 10G SFP+ Port (Optional): If you require 10 Gigabit connectivity, insert a compatible 10G SFP+ module (not included) into the SFP+ port (labeled 6(10G)). Then, connect a suitable fiber optic cable or DAC cable to the SFP+ module. Ensure the SFP+ module and connected device are compatible.

Figure 3.2: Illustration of cable requirements for achieving 2.5Gbps and 10Gbps speeds. CAT6, CAT6a, and CAT7 cables are recommended for optimal performance.
Nota importante: To achieve 2.5Gbps or 10Gbps network speeds, ensure that all components in your network path, including network cards, routers, and cables, support these higher speeds. If any device operates at a lower speed (e.g., 1Gbps), the connection speed will default to the lowest common speed.
4. Istruzioni per l'uso
The Real HD 5 Port 2.5Gb Ethernet Switch is an unmanaged device, meaning it operates on a plug-and-play basis without requiring any software configuration. Once connected, it automatically detects and configures the speed and duplex mode of connected devices.
Indicatori LED:
Il pannello frontale dello switch è dotato di indicatori LED per fornire informazioni sullo stato:
- LED PWR (alimentazione):
- SU: L'interruttore è acceso.
- Spento: L'interruttore è spento.

5. Manutenzione
Proper maintenance ensures the longevity and reliable operation of your Real HD Ethernet Switch.
5.1 Cura generale
- Pulizia: Utilizzare un panno morbido e asciutto per pulire l'esterno dell'interruttore. Non utilizzare detergenti liquidi o spray.
- Ambiente: Operate the switch within its specified temperature range (-20 to 50℃). Avoid placing it in areas with high humidity, dust, or extreme temperatures.
- Ventilazione: Ensure that the ventilation holes on the sides of the switch are not blocked to allow for proper heat dissipation, even though it is a fanless design.
- Energia: Use only the provided power adapter. Disconnect power during electrical storms or when unused for extended periods.

6. Risoluzione Dei Problemi
Se riscontri problemi con il tuo switch, fai riferimento ai seguenti problemi comuni e alle relative soluzioni:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessuna alimentazione (LED PWR spento) | Adattatore di alimentazione non collegato o difettoso; presa di corrente non funzionante. | Ensure the power adapter is securely connected to the switch and a working power outlet. Test the outlet with another device. |
| No Link Light for a Connected Device | Ethernet cable faulty or improperly connected; device is off or faulty; incorrect cable type. | Check cable connections at both ends. Try a different Ethernet cable. Ensure the connected device is powered on and functioning correctly. Verify you are using CAT6 or higher for 2.5G connections. |
| Velocità di rete lenta | Connected device does not support 2.5Gbps; cable type is insufficient (e.g., CAT5e for 2.5G); network congestion. | Ensure all devices in the network path (including network cards) support 2.5Gbps. Use CAT6 or higher pure copper Ethernet cables. Check for other network activity that might be consuming bandwidth. |
| SFP+ Port Not Functioning | SFP+ module not inserted correctly or incompatible; fiber/DAC cable faulty. | Ensure the SFP+ module is fully inserted and compatible with the switch. Check the fiber optic or DAC cable for damage and proper connection. Ensure the connected device supports 10Gbps. |
