4. 제품 특징
- Integrated Industrial PoE Switch Module: Features 8 full Gigabit PoE+ ports and 2 SFP slots. Supports IEEE802.3af/at protocol, providing a maximum of 30W per port and a total power budget of 300W for the entire device.
- IP55 보호 수준: Industrial-grade protection against dust, water, shock, weather, and electromagnetic radiation. The enclosure includes a lock and key to prevent theft.
- 번개 보호: Integrated surge arrester and air circuit breaker effectively prevent lightning strikes and overloads (6 kV lightning protection).
- 내구성이 뛰어나고 견고한 구조: The enclosure is made from 1.2 mm thick galvanized steel sheet, ensuring high durability and rust prevention. Dimensions: 13.39 x 9.65 x 9.45 inches (34 x 24.5 x 24 cm).
- 팬 냉각: Equipped with an integrated cooling fan, allowing the machine to operate within a temperature range of -20°C to 75°C (4°F to 167°F).
- Advanced Functions (DIP Switches): Includes 4 built-in DIP switches for:
- AI PoE: Intelligent PoE management.
- Ultra Long-Distance Transmission: Extends transmission up to 820.21 feet (250 meters). Note: Bandwidth will drop to 10 Mbps in this mode.
- 포트 격리: Isolates ports for enhanced security.
- QoS(서비스 품질): Prioritizes network traffic.

6. 사용 설명서
6.1 전원 켜기
After all connections are secure, switch the air circuit breaker to the ON position. The device will power on, and connected PoE devices will receive power automatically.
6.2 딥 스위치 기능
The switch features four DIP switches to enable specific functions:
- AI PoE: When enabled, the switch intelligently manages PoE power, detecting and restarting unresponsive PoE devices.
- Long-Distance Transmission (250m): Activates extended range mode for PoE ports, allowing data and power transmission up to 250 meters. Note that in this mode, the port speed will be reduced to 10 Mbps.
- 포트 격리: Isolates individual PoE ports, preventing direct communication between devices connected to these ports, enhancing security.
- QoS(서비스 품질): Prioritizes network traffic for critical applications, ensuring smoother performance for video streams or voice communications.

7. 유지관리
- 정기 검사: 주기적으로 외함에 손상, 부식 또는 느슨한 연결부가 있는지 점검하십시오.
- 청소: Keep the exterior of the enclosure clean. For internal cleaning, ensure power is disconnected and use a soft, dry cloth. Do not use liquid cleaners.
- 팬 작동 : Ensure the cooling fan is free from obstructions and operating correctly to maintain optimal internal temperature.
- 보안: Always keep the enclosure locked to protect internal components and prevent unauthorized access.
8. 문제 해결
- 전원 없음: Check the power source, the air circuit breaker, and all power cable connections. Ensure the power indicator light is on.
- 네트워크 연결 없음: Verify Ethernet cable connections to both the switch and the connected devices. Check the link/activity LEDs on the ports. Ensure DIP switch settings are appropriate for your network configuration.
- PoE 장치가 켜지지 않음: Confirm the connected device is PoE compatible (IEEE802.3af/at). Check the PoE status LED for the specific port. Ensure the total power consumption does not exceed the 300W budget. If AI PoE is enabled, the switch may attempt to restart the device.
- 네트워크 속도가 느립니다: If using the long-distance transmission mode, expect a speed reduction to 10 Mbps. Check for network congestion or faulty cables.
- Lightning Protection Tripped: If the air circuit breaker trips, it indicates a power surge. Inspect the power line and connected devices for damage before resetting the breaker.
