3.3 Device Layout
Figure 1: MOXA EDS-305-M-SC-T Industrial Unmanaged Ethernet Switch. This image shows three industrial switches mounted on a DIN rail, illustrating their compact form factor and typical installation environment.
The EDS-305-M-SC-T features a robust metal casing with various ports and LED indicators on its front panel. Key components include:
- Ethernet Ports: 4 x 10/100BaseTX RJ45 ports for copper cable connections.
- Fiber Port: 1 x 100BaseFX SC connector for multi-mode fiber optic cable.
- LED Indicators: Power (PWR), Fault, and Link/Act LEDs for each port.
- Terminal Block: For power input (V+, V-, GND) and relay output connections.
4. Setup
4.1 Mounting the Switch
The EDS-305-M-SC-T is designed for DIN-rail mounting. Follow these steps:
- Hook the top of the DIN-rail clip onto the DIN rail.
- Press the switch firmly against the DIN rail until the clip snaps into place.
- Ensure the switch is securely fastened to the DIN rail.
4.2 Wiring the Network Connections
Ethernet Ports (RJ45):
- Connect standard Cat5/5e/6 Ethernet cables from your network devices (e.g., PCs, PLCs, IP cameras) to the RJ45 ports on the switch.
- The switch supports auto MDI/MDI-X, so straight-through or crossover cables can be used.
Fiber Optic Port (SC):
- Connect a multi-mode fiber optic cable with SC connectors to the 100BaseFX port.
- Ensure the transmit (TX) fiber from one device connects to the receive (RX) fiber of the other device, and vice-versa.
4.3 Power Connection
The EDS-305-M-SC-T supports redundant dual DC power inputs. Use the provided terminal block for power connections.
- Ensure the power source is within the specified voltage range (e.g., 12-48 VDC).
- Connect the positive wire to the V+ terminal, the negative wire to the V- terminal, and the ground wire to the GND terminal on the terminal block.
- Insert the wired terminal block into the power input slot on the switch.
- Apply power to the switch. The PWR LED should illuminate.
4.4 Relay Output Connection
The smart relay output can be connected to an external alarm device (e.g., a buzzer or light) to signal network events or power failures.
- Connect the alarm device to the relay output terminals on the terminal block.
- Refer to the device's specific wiring diagram for correct polarity and connection.
5. Operating
5.1 Basic Operation
The EDS-305-M-SC-T is an unmanaged switch, meaning it operates as plug-and-play. Once powered on and connected to network devices, it automatically forwards Ethernet frames between connected ports. No software configuration is required for basic network operation.
5.2 LED Indicators
Monitor the LED indicators on the front panel to check the switch's status and network activity:
- PWR LED: Illuminates green when power is supplied to the switch.
- FAULT LED: Illuminates red when a power input failure occurs.
- Link/Act LEDs (RJ45 Ports):
- Green (Solid): Indicates a valid network link.
- Green (Flashing): Indicates network activity (data transmission/reception).
- Link/Act LED (Fiber Port):
- Green (Solid): Indicates a valid fiber optic link.
- Green (Flashing): Indicates fiber optic network activity.
6. Maintenance
6.1 Cleaning
Periodically clean the exterior of the switch with a soft, dry cloth. Do not use liquid or aerosol cleaners. Ensure the device is powered off before cleaning.
6.2 Connection Checks
Regularly inspect all cable connections (Ethernet, fiber, power, relay) to ensure they are secure and free from damage. Loose or damaged connections can lead to intermittent network issues or device malfunction.
7. Troubleshooting
If you encounter issues with your EDS-305-M-SC-T switch, refer to the following troubleshooting tips:
- No Power: Check the power supply connection and ensure the power source is active. Verify the PWR LED is illuminated.
- No Link on Ethernet Port: Ensure the Ethernet cable is securely connected at both ends. Check the cable for damage. Verify the connected device is powered on and functioning correctly.
- No Link on Fiber Port: Ensure the fiber optic cable is securely connected and not damaged. Verify the TX/RX polarity is correct. Check the connected fiber device for proper operation.
- Network Connectivity Issues: If multiple devices are affected, check the upstream network devices. Ensure there are no IP address conflicts if static IPs are used on connected devices.
- FAULT LED is ON: This indicates a power input failure. Check the power connections and the power supply unit.
If problems persist after attempting these steps, please contact MOXA technical support for further assistance.
