- Fiber Ports (7-8): SC connectors for 100BaseFX multi-mode fiber optic connections.
- Power Inputs (P1, P2): Terminal block for redundant power connections.
- LED Indicators: Status lights for power (P1, P2) and port link/activity.
3. Setup
3.1 Mounting
The EDS-208A-MM-SC is designed for DIN-rail mounting. Ensure the mounting surface is stable and provides adequate ventilation. Attach the DIN-rail kit to the switch and then secure it onto a standard DIN rail.
3.2 Power Connection
Connect the power source to the terminal block located on the top of the switch. The switch supports redundant dual 12/24/48 VDC or 18 to 30 VAC inputs. Ensure correct polarity for DC power. Use appropriate gauge wiring for industrial environments.
3.3 Network Connection
Connect your network devices to the switch using standard Ethernet cables for the RJ45 ports (1-6) or multi-mode fiber optic cables with SC connectors for the fiber ports (7-8). Ensure all cables are securely connected.
4. Operating Instructions
The MOXA EDS-208A-MM-SC is an unmanaged switch, meaning it operates automatically without requiring software configuration. Once powered on and connected, it will begin forwarding data.
4.1 Power On
After connecting the power supply, the P1 and/or P2 LEDs on the front panel will illuminate, indicating that the switch is receiving power.
4.2 LED Indicators
- P1/P2 LEDs: On when power input P1/P2 is active.
- Link/Act LEDs (per port):
- Solid Green: Indicates a valid network link is established.
- Flashing Green: Indicates data activity (transmitting or receiving).
- Off: No link or connection.
The switch automatically detects the speed and duplex mode of connected devices (Auto MDI/MDI-X for RJ45 ports).
5. Maintenance
The EDS-208A-MM-SC is designed for minimal maintenance. However, periodic checks can ensure optimal performance.
- Cleaning: Keep the switch and its ports free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Environmental Check: Ensure the operating environment remains within the specified temperature and humidity ranges (-10 to 60°C).
- Cable Integrity: Periodically inspect all connected cables for damage or loose connections.
- Power Supply: Verify that the power supply is stable and within the specified voltage range.
6. Troubleshooting
If you encounter issues with your EDS-208A-MM-SC switch, refer to the following common troubleshooting steps:
- No Power (P1/P2 LEDs Off):
- Check the power cable connection to the switch and the power source.
- Verify the power supply is functioning correctly and providing the correct voltage.
- Ensure the terminal block wiring is secure and correctly polarized.
- No Link (Link/Act LED Off):
- Ensure the Ethernet or fiber cable is securely connected at both ends.
- Verify the connected device is powered on and functioning correctly.
- Check the cable for damage. Try a different cable if available.
- For fiber connections, ensure the correct fiber type (multi-mode) and SC connectors are used, and that the transmit (Tx) and receive (Rx) fibers are correctly connected.
- Slow Network Performance:
- Check for excessive network traffic or bottlenecks elsewhere in the network.
- Ensure all connected devices are operating at their optimal speed and duplex settings (though the switch is unmanaged, device settings can impact overall performance).
- Inspect cables for damage or degradation.
If problems persist, contact Moxa technical support for further assistance.
