Troubleshooting
This section provides solutions to common issues you might encounter with your EL900-A-H-1-B media converter.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power LED (PWR) | No power supply; incorrect voltage; faulty power connection. | Check power source, verify voltage, ensure secure power connections. |
| No Link on Fiber (FX Link/Act) | Damaged fiber cable; incorrect fiber type; faulty SFP module (if applicable); distant end device off. | Inspect fiber cable, ensure correct fiber type, check SFP module, verify distant end device is operational. |
| No Link on Ethernet (TX Link/Act) | Damaged Ethernet cable; incorrect cable type (straight-through/crossover); faulty network card; distant end device off. | Inspect Ethernet cable, ensure correct cable type, check network card, verify distant end device is operational. |
| Data not transmitting | Link established but no data flow; incorrect DIP switch settings. | Check network configuration on connected devices. Verify DIP switch settings against the product datasheet. |
