- RJ45 Ports (1-5): These ports support 10/100/1000 Mbps Ethernet connections. They automatically detect the speed of the connected device and adjust accordingly.
- LED Indicators: Each port has an associated LED. A solid green light indicates a stable link at 1000 Mbps. A solid orange light indicates a stable link at 10/100 Mbps. A blinking light indicates data activity.
3.2 Rear Panel
The rear panel typically contains the power input port.
- Power Port: Connect the provided power adapter here.
4. Setup
The MS105G switch is designed for simple plug-and-play installation. Follow these steps to set up your device:
- Power Off Devices: Disconnect the power from your router, modem, and any devices you plan to connect to the switch.
- Connect the Switch:
- Connect your modem or router to any of the RJ45 ports on the MS105G using an Ethernet cable.
- Connect your network devices (e.g., computers, smart TVs, game consoles, network printers) to the remaining RJ45 ports on the MS105G using Ethernet cables.
- Connect Power: Connect the provided power adapter to the power port on the MS105G, then plug the adapter into a standard electrical outlet.

5. Operating Instructions
The MERCUSYS MS105G is a non-managed switch, meaning it operates automatically without requiring any user configuration. Once connected as described in the Setup section, it will begin forwarding data between connected devices.
- Automatic Negotiation: Each port automatically detects the speed (10/100/1000 Mbps) and duplex mode (Half/Full Duplex) of the connected device.
- Auto MDI/MDIX: The switch automatically detects if a straight-through or crossover cable is needed, eliminating the need for specific cable types.
- LED Indicators: Observe the LED indicators on the front panel to confirm link status and activity for each port.
6. Maintenance
To ensure optimal performance and longevity of your MS105G switch, consider the following maintenance guidelines:
- Placement: Place the switch in a cool, dry location away from direct sunlight, heat sources, and excessive moisture. Ensure adequate ventilation around the device.
- Cleaning: Use a soft, dry cloth to clean the exterior of the switch. Do not use liquid or aerosol cleaners.
- Cable Management: Keep Ethernet cables neatly organized to prevent tangles and accidental disconnections.
- Power Supply: Use only the power adapter provided with the device.
7. Troubleshooting
If you encounter issues with your MS105G switch, refer to the following common troubleshooting steps:
- No Power:
- Ensure the power adapter is securely connected to the switch and a working electrical outlet.
- Verify the power outlet is functional by plugging in another device.
- No Link/Activity on a Port:
- Check that the Ethernet cable is securely connected to both the switch port and the connected device.
- Try a different Ethernet cable to rule out a faulty cable.
- Ensure the connected device is powered on and its network adapter is functioning correctly.
- Try connecting the device to a different port on the switch.
- Slow Network Speed:
- Ensure all connected devices and cables support Gigabit Ethernet (Cat5e or Cat6 cables are recommended for Gigabit speeds).
- Check the LED indicator for the port; a green light indicates a Gigabit connection, while an orange light indicates 10/100 Mbps.
- Restart your modem, router, and the switch.
