4. Installation
4.1. Safety Precautions
For the safe installation and operation of the switch, we recommend that you:
- Check if the power cord is securely wrapped around the AC power connector.
- Ensure proper heat dissipation and ventilation around the switch.
- Do not stack heavy objects on top of the switch.
4.2. Desktop Installation
When installing the media converter on a desktop, the device must be placed horizontally and kept stable. Ensure sufficient space between the device and surrounding objects for proper ventilation.
4.3. Power Connection
The switch adapter uses a two-wire power socket. The power cord uses a single-phase three-wire power socket, with the middle pin as the grounding wire, the left pin as the neutral wire, and the right pin as the live wire. Please check before operation.
- Verify that the power supply matches the power supply indicated on the switch.
- Connect the adapter and power cord+adapter directly to an AC 100~240V, 50/60Hz mains power outlet.
4.4. SFP Port Connection
To install fiber optic modules:
- Grasp the fiber optic module from the side.
- Smoothly insert it along the SFP port slot of the switch until the fiber optic module is in firm contact with the switch.

4.5. Post-Installation Check
After installation, please check the following:
- Is there sufficient heat dissipation space around the switch, and is the air circulation smooth?
- Does the power supply of the power socket meet the specifications of the switch?
- Are the power supply, switches, racks, and other equipment properly grounded?

8. Troubleshooting
If you encounter issues with your media converter, consider the following common troubleshooting steps:
- No Power: Check the PWR LED indicator. If it's off, ensure the power adapter is securely connected and the power outlet is functional. If it blinks, there might be a port short circuit or excessive load current.
- No Link/Connection: If the Link LED for either the RJ45 or SFP+ port is off, verify that the cables are correctly connected and not damaged. Ensure the optical module (if used) is properly seated and compatible.
- Incorrect Speed: If the R/G LED indicates an unexpected speed (e.g., green for 2.5G when 10G is expected, or red for 10G when 2.5G is expected), check the connected device's speed settings and cable compatibility. Ensure the SFP+ module supports the desired speed.
- Data Transfer Issues: If the Link LED is on but not blinking, there might be no data transfer. Check the network configuration of connected devices.
- Overheating: Ensure the device has adequate ventilation. Multiple cooling holes on both sides provide multi-hole ventilation and heat dissipation to prevent high-temperature overloading.
- Lightning Protection: The device features 6KV lightning protection. However, in severe thunderstorms, it's advisable to disconnect the device if possible.
