5. Setup and Installation

5.1 Mounting

The TN-5308-8PoE-48-T supports DIN-rail mounting or panel mounting. Follow the instructions provided with the mounting kit for secure installation.

• DIN-rail Mounting: Attach the DIN-rail bracket to the switch, then snap the switch onto a standard DIN-rail.
• Panel Mounting: Use screws to secure the switch directly to a panel or wall through the designated mounting holes.

5.2 Grounding the Switch

Proper grounding is crucial for electromagnetic compatibility (EMC) and surge protection. Connect the grounding screw on the switch to a reliable ground source using a grounding wire.

5.3 Power Connection

Connect a 48 VDC power supply to the M12 L-coded power input connector. Ensure the polarity is correct. The isolated power input enhances reliability in industrial environments.

5.4 Network Connection

Connect Ethernet devices (e.g., IP cameras, wireless access points, other switches) to the 10/100BaseT(X) PoE ports using M12 A-coded Ethernet cables. The switch will automatically detect the link speed and provide power to PoE-compatible devices.

6. Operating the Switch

The Moxa TN-5308-8PoE-48-T is an unmanaged switch, meaning it operates plug-and-play without requiring any software configuration. Once powered on and connected, it will automatically forward Ethernet frames between connected devices.

7. Maintenance

The TN-5308-8PoE-48-T is designed for minimal maintenance. However, periodic checks can help ensure optimal performance:

• Cleaning: Keep the device free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid or aerosol cleaners.
• Cable Inspection: Periodically inspect all M12 cables for damage or loose connections.
• Environmental Check: Ensure the operating environment remains within the specified temperature and humidity ranges.

8. Troubleshooting

If you encounter issues with your Moxa TN-5308-8PoE-48-T switch, refer to the following common troubleshooting steps:

• No Power (PWR LED Off):
  • Check the power supply connection to the M12 L-coded connector.
  • Verify the power source is providing 48 VDC.
  • Ensure the power supply is functioning correctly.
• No Link (Link/Act LED Off):
  • Ensure the Ethernet cable is securely connected to both the switch port and the connected device.
  • Verify the connected device is powered on and functioning.
  • Try a different M12 Ethernet cable.
  • Test with a different port on the switch.
• PoE Not Working (PoE LED Off):
  • Confirm the connected device is PoE-compatible (IEEE 802.3af/at).
  • Check the PoE cable connection.
  • Ensure the total power budget of the switch is not exceeded by all connected PoE devices.

If the problem persists after trying these steps, contact Moxa technical support.
