5. Operating Instructions
The ZYXEL GS-108S v2 is an unmanaged switch, which means it operates on a plug-and-play basis without requiring any software configuration or management. Once connected and powered on, the switch automatically detects the speed and duplex mode of connected devices.
Quality of Service (QoS): The switch incorporates Quality of Service features to prioritize network traffic. It includes two high-priority ports and two medium-priority ports. This allows for optimization of network performance for specific applications, such as video streaming or online gaming, by ensuring that traffic from devices connected to these designated ports receives preferential bandwidth. Refer to the port numbering on the device for specific priority assignments.
6. Maintenance
- Cleaning: Keep the switch clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid or aerosol cleaners.
- Ventilation: Ensure proper airflow around the switch to prevent overheating. Do not block ventilation openings.
- Casing: Do not attempt to open the casing of the switch. There are no user-serviceable parts inside.
7. Troubleshooting
- No Power:
- Check if the power adapter is securely connected to the switch and the power outlet.
- Verify that the power outlet is functional by plugging in another device.
- No Link Light for a Connected Device:
- Ensure the Ethernet cable is securely connected at both ends (switch and network device).
- Try a different Ethernet cable to rule out a faulty cable.
- Verify that the connected device is powered on and its network adapter is functioning correctly.
- Slow Network Speed:
- Ensure all connected devices and Ethernet cables support Gigabit Ethernet (Cat5e or higher) for optimal performance.
- Check for excessive network traffic or bandwidth-intensive applications running on your network.
- Verify the integrity of your Ethernet cables; damaged cables can reduce network speed.
