4. දෘඩාංග විස්තරය
The IMC-21A-S-SC features a robust design with clearly labeled ports and LED indicators for easy monitoring and setup.

Figure 1: Front Panel of IMC-21A-S-SC Media Converter
The image displays the front panel of the Moxa IMC-21A-S-SC Industrial Media Converter. Visible components include the PWR LED, RX and TX fiber optic ports (SC connector type), 100M LED, FDX/COL LED, and the 10/100BaseTX Ethernet port (RJ45). The model number IMC-21A is printed at the bottom.
4.1. LED දර්ශක
- PWR: Indicates power status. Lit when the device is powered on.
- 100M (Fiber): Lit when the fiber optic link is established at 100 Mbps.
- FDX/COL (Fiber): Lit for Full Duplex mode; flashes for collision detection in Half Duplex mode.
- 100M (Ethernet): Lit when the Ethernet link is established at 100 Mbps.
- 10M (Ethernet): Lit when the Ethernet link is established at 10 Mbps.
4.2. වරායන්
- 10/100BaseTX (RJ45): Standard Ethernet port for connecting to copper-based network devices. Supports auto-negotiation.
- 100BaseFX (SC Connector): Fiber optic port for single-mode fiber connections. RX (Receive) and TX (Transmit) are clearly marked.
5. ස්ථාපනය
5.1 සවි කිරීම
The IMC-21A-S-SC can be DIN-rail mounted or wall-mounted. Ensure adequate ventilation around the device.
- DIN-Rail සවි කිරීම: Attach the DIN-rail kit (if not pre-installed) to the rear of the converter. Snap the converter onto a standard DIN rail.
- බිත්ති සවි කිරීම: Use screws to secure the device to a wall or panel through the provided mounting holes.
5.2. බල සම්බන්ධතාවය
Connect a compatible DC power supply (not included) to the terminal block on the top of the device. Ensure correct polarity. The PWR LED will illuminate upon successful power connection.
5.3. ජාල සම්බන්ධතා
- ඊතර්නෙට් සම්බන්ධතාවය: Connect an RJ45 Ethernet cable from your network device (e.g., switch, PC) to the 10/100BaseTX port on the converter.
- Fiber Optic Connection: Connect a single-mode fiber optic cable with SC connectors to the 100BaseFX RX and TX ports. Ensure that the TX port of one device connects to the RX port of the other, and vice-versa.
6. මෙහෙයුම
Once all connections are made and power is supplied, the IMC-21A-S-SC will automatically establish the network links. Observe the LED indicators to confirm proper operation:
- ද පීඩබ්ලිව්ආර් LED should be steadily lit.
- ද 100M (Fiber) LED should be lit if a 100 Mbps fiber link is established.
- ද FDX/COL (Fiber) LED should be lit for full-duplex operation.
- ද 100M or 10M (Ethernet) LED should be lit, indicating the established Ethernet speed.
Data transmission will occur transparently between the Ethernet and fiber optic segments.
7. නඩත්තු කිරීම
The IMC-21A-S-SC is designed for minimal maintenance. However, periodic checks can ensure optimal performance:
- උපාංගය පිරිසිදුව හා දූවිලි වලින් තොරව තබා ගන්න. පිරිසිදු කිරීම සඳහා මෘදු වියළි රෙද්දක් භාවිතා කරන්න.
- Inspect fiber optic connectors for cleanliness. Use appropriate fiber cleaning tools if necessary.
- Ensure all cables are securely connected and not damaged.
- මෙහෙයුම් පරිසරය නිශ්චිත උෂ්ණත්ව හා ආර්ද්රතා පරාසයන් තුළ පවතින බව තහවුරු කර ගන්න.
8. දෝශ නිරාකරණය
If you encounter issues with your IMC-21A-S-SC, refer to the following common problems and solutions:
| ගැටලුව | විය හැකි හේතුව | විසඳුම |
|---|---|---|
| විදුලිය නැත (PWR LED අක්රියයි) | No power supply, incorrect connection, faulty power supply. | Check power cable and terminal block connection. Verify power supply output. |
| No Fiber Link (100M Fiber LED off) | Incorrect fiber connection, damaged fiber cable, incompatible fiber type, faulty transceiver. | Ensure TX connects to RX. Check fiber cable for damage. Verify single-mode fiber usage. Clean SC connectors. |
| No Ethernet Link (100M/10M Ethernet LED off) | Incorrect Ethernet cable, damaged cable, connected device off/faulty. | Check RJ45 cable connection. Test with a known good cable. Ensure the connected Ethernet device is operational. |
| මන්දගාමී ජාල කාර්ය සාධනය | Duplex mismatch, network congestion. | Check FDX/COL LED. Ensure connected devices are set to auto-negotiation or matching duplex settings. |
If the problem persists, contact Moxa technical support for further assistance.
