Installation and Maintenance Instructions:
- Installation:
- The HIRSCHMANN MM3-2FXM4/2TX1 is designed for DIN rail mounting in industrial control panels or network cabinets. Ensure that the installation location provides adequate ventilation and space for airflow around the module.
- Connect the fiber optic cables to the SC or ST ports for long-distance communication between network devices. Depending on the version, the module supports different fiber types (multimode or singlemode).
- The copper ports can be connected to local Ethernet devices like computers, switches, or other control systems via standard Ethernet cables.
- Connect the 24V DC power supply to the redundant power input terminals, ensuring the module receives stable power for uninterrupted operation.
- For redundancy, ensure both power inputs are connected to separate power sources for improved reliability.
- Confirm all connections are secure and follow the recommended wiring diagrams provided by HIRSCHMANN to avoid any electrical issues.
- Maintenance:
- Regular Inspection: Inspect the MM3-2FXM4/2TX1 module periodically for any physical damage, such as loose connections or signs of wear.
- Check Power Supply: Ensure that the power supply is stable and within the required voltage range. Check for any power-related alarms in the network management system.
- Cleaning: Clean the module periodically to prevent dust buildup, which could affect the cooling performance. Use a soft cloth to clean the exterior, avoiding any abrasive materials.
- Cable Inspection: Regularly check the fiber optic cables for any damage or signs of wear. Ensure that there is no bending or kinking, as this can degrade signal quality.
- System Monitoring: Use HIRSCHMANN’s network management tools to monitor the status of the module and identify any potential issues such as network congestion, fiber link loss, or power interruptions.
- Troubleshooting:
- No Communication on Fiber Ports: Verify that the fiber optic cables are securely connected to the correct ports and that the connectors are clean. Check the fiber type (singlemode or multimode) and ensure it matches the module’s configuration.
- Ethernet Ports Not Functioning: Ensure that the Ethernet cables are correctly connected and that the devices on the other end of the copper ports are powered on and functioning properly. Check the network speed settings to ensure compatibility with the connected devices.
- Power Failure: If the module does not power on, check the power supply and ensure that the 24V DC input is connected properly. Verify that both power inputs are functional for redundancy.
- Error Indicators: Check the status LEDs on the module for any error codes or warnings. Refer to the user manual for guidance on interpreting these LED indicators.
