3.2. DIP-переключатели
The FVT-2202 features DIP switches for advanced configuration. Refer to the markings on the device for specific switch functions, which typically include settings for LFP (Link Fault Pass-through), speed, and duplex mode.
- Переключатель 1: LFP (Link Fault Pass-through) Enable/Disable
- Переключатель 2: Auto-Negotiation Enable/Disable
- Переключатель 3: 100Mbps/10Mbps Speed Selection (when Auto-Negotiation is disabled)
- Переключатель 4: Full-Duplex/Half-Duplex Selection (when Auto-Negotiation is disabled)
Осторожность:
Ensure the device is powered off before changing DIP switch settings to prevent potential damage or incorrect configuration.
4. Настройка и установка
Follow these steps to properly install and connect your LevelOne FVT-2202 Media Converter:
- Подготовка окружающей среды: Ensure the installation location is clean, dry, and has adequate ventilation. Avoid areas with extreme temperatures or humidity.
- Выключите устройства: Before making any connections, ensure that all network devices (switches, routers, computers) that will connect to the media converter are powered off.
- Configure DIP Switches (if necessary): If specific network settings are required (e.g., fixed speed/duplex, LFP), adjust the DIP switches on the rear of the converter according to your network requirements. Refer to Section 3.2 for details.
- Подключите оптоволоконный кабель: Connect one end of the fiber optic cable (SC connector) to the FX port on the FVT-2202. Connect the other end to your fiber optic network device (e.g., fiber switch, another media converter). Ensure the transmit (TX) and receive (RX) fibers are correctly matched.
- Подключите кабель Ethernet: Connect a standard RJ45 Ethernet cable from your copper-based network device (e.g., Ethernet switch, computer) to the TX port on the FVT-2202.
- Подключите адаптер питания: Plug the provided 5VDC power adapter into the power input jack on the FVT-2202. Then, plug the power adapter into a suitable electrical outlet.
- Включите устройства: Power on the FVT-2202. The PWR LED should illuminate green. Then, power on your connected network devices.
- Проверьте соединения: Check the Link/Act LEDs for both the FX (fiber) and TX (Ethernet) ports. A solid green light indicates a successful link. Blinking lights indicate data activity.
Важный:
Always handle fiber optic cables with care. Avoid bending them sharply or exposing the connectors to dust and dirt, which can degrade performance.
5. Операция
Once the LevelOne FVT-2202 is properly installed and powered on, it operates automatically as a transparent media converter. It translates Ethernet signals between copper and fiber optic mediums without requiring any software configuration.
5.1. Базовая функциональность
- The converter transparently passes Ethernet frames between the RJ45 (copper) and SC (fiber) interfaces.
- It supports both 10Mbps and 100Mbps Fast Ethernet speeds.
- Auto-negotiation is typically enabled by default on the RJ45 port to automatically detect the speed and duplex mode of the connected device.
- The fiber optic port operates at 100Mbps full-duplex.
5.2. Состояние мониторинга
The LED indicators provide a quick visual status of the converter's operation:
- Светодиод PWR: Confirms the device is powered.
- FX Link/Act LED: Indicates the status of the fiber optic link and data activity.
- TX Link/Act LED: Indicates the status of the Ethernet link and data activity.
Refer to Section 3.1 for a detailed explanation of LED behaviors.
6. Техническое обслуживание
The LevelOne FVT-2202 Media Converter is designed for minimal maintenance. However, following these guidelines can help ensure its longevity and reliable performance:
- Уборка: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning the exterior. Do not use liquid or aerosol cleaners.
- Fiber Optic Connectors: Ensure fiber optic connectors are clean. Dust or dirt on the fiber end-faces can significantly degrade signal quality. Use appropriate fiber optic cleaning tools if necessary.
- Вентиляция: Убедитесь, что вентиляционные отверстия на устройстве не заблокированы, чтобы предотвратить перегрев.
- Источник питания: Use only the power adapter provided with the device. Using an incorrect power adapter can damage the converter.
- Условия окружающей среды: Operate the device within its specified environmental conditions (temperature, humidity) to prevent malfunction.
7. Поиск Неисправностей
If you encounter issues with your LevelOne FVT-2202 Media Converter, refer to the following troubleshooting steps:
| Проблема | Возможная причина | Решение |
|---|---|---|
| Нет питания (светодиод PWR выключен) | Адаптер питания не подключен или неисправен. | Check power adapter connection to the device and wall outlet. Ensure the outlet is functional. Try a different power adapter if available and compatible. |
| No Fiber Link (FX Link/Act LED Off) | Fiber cable disconnected, damaged, or incorrect TX/RX connection. | Verify fiber cable connections at both ends. Ensure TX/RX are correctly matched. Inspect cable for damage. Clean fiber connectors. Check the remote fiber device. |
| No Ethernet Link (TX Link/Act LED Off) | Ethernet cable disconnected, damaged, or incorrect speed/duplex settings. | Verify Ethernet cable connection. Inspect cable for damage. Ensure the connected device is powered on and functioning. Check DIP switch settings for speed/duplex if auto-negotiation is disabled. |
| Poor Network Performance | Cable issues, duplex mismatch, or excessive network traffic. | Check cable quality and length. Ensure duplex settings are consistent across connected devices (auto-negotiation recommended). Monitor network traffic. |
