Setup Instructions
The NETGEAR MS308 switch is designed for simple plug-and-play operation, requiring no software installation or configuration. Follow these steps to set up your switch:
- Placement: Choose a suitable location for the switch. It can be placed on a desktop or mounted on a wall using the included wall installation kit. Ensure adequate ventilation around the device.
- Connect Power: Connect the power adapter to the switch's power input and then plug the adapter into a power outlet. The Power LED on the front of the switch will illuminate.
- Connect Devices: Use standard Ethernet cables (Cat5e or higher recommended for 2.5G speeds) to connect your network devices (e.g., computers, servers, network-attached storage (NAS), Wi-Fi access points) to any of the 8 Ethernet ports on the switch.
- Verify Connection: Once connected, the corresponding LED for each active port will light up, indicating a successful connection. The color of the LED indicates the link speed (refer to the Operating section for details).


Operating the Switch
The NETGEAR MS308 is an unmanaged switch, meaning it operates automatically without requiring user configuration. Simply connect your devices, and the switch will handle data traffic efficiently.
LED Indicators
The front panel of the switch features LED indicators that provide status information:
- Power LED:
- Solid Green: The switch is powered on.
- Link/Activity LEDs (for each port):
- Solid Green (Both): 2.5 Gigabit connection.
- Solid Green (Left): 1 Gigabit connection.
- Solid Green (Right): 100 Megabit connection.
- Blinking: Activity on the port (data transmission).
- Off: No link or device connected.


Maintenance
The NETGEAR MS308 switch is designed for reliable, long-term operation with minimal maintenance. Consider the following for optimal performance:
- Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth to wipe the exterior. Avoid using liquid cleaners or aerosols.
- Ventilation: Ensure that the ventilation openings are not blocked to prevent overheating.
- Firmware: As an unmanaged switch, the MS308 typically does not require firmware updates. However, for other NETGEAR products, always check the official NETGEAR support website for the latest firmware and updates.
Troubleshooting
If you encounter issues with your NETGEAR MS308 switch, refer to the following common troubleshooting steps:
- No Power:
- Ensure the power adapter is securely connected to the switch and a working power outlet.
- Verify the power outlet is functional by plugging in another device.
- No Link Light:
- Check that the Ethernet cable is securely connected to both the switch port and the network device.
- Try a different Ethernet 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:
- Verify that your Ethernet cables are rated for the desired speed (Cat5e or higher for 2.5G).
- Check the Link/Activity LED color to confirm the negotiated speed (Both Green for 2.5G, Left Green for 1G, Right Green for 100M).
- Ensure your connected devices (e.g., network adapter, router) also support 2.5G speeds.
- Temporarily disconnect other devices to see if network congestion is the cause.
