3. Tohutohu Tatūnga
Follow these steps to set up your Real HD 5 Port 2.5Gb Ethernet Switch.
3.1 Te Whakanoho a tinana
- 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.

- Hono Hono: 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.

5. Tiaki
Proper maintenance ensures the longevity and reliable operation of your Real HD Ethernet Switch.
5.1 Tiakitanga Whanui
- Te horoi: Whakamahia he kakahu ngohengohe, maroke hei horoi i waho o te whakawhiti. Kaua e whakamahi i te wai, i te horoi aerosol ranei.
- Taiao: Operate the switch within its specified temperature range (-20 to 50℃). Avoid placing it in areas with high humidity, dust, or extreme temperatures.
- Whakahau: 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.
- Mana: Whakamahia anake te urutau hiko kua whakaratohia. Momotuhia te hiko i te wā e kore e whakamahia ana, ina kore rānei e whakamahia mō ngā wā roa.
