5.2 기본 구성

Within the QSS interface, you can configure various network settings:

• VLAN : Create Virtual Local Area Networks to segment network traffic.
• QoS(서비스 품질): Prioritize specific types of network traffic for improved performance.
• LACP(링크 집계 제어 프로토콜): 여러 개의 물리적 링크를 하나의 논리적 링크로 결합하여 대역폭과 중복성을 높입니다.
• IGMP 스누핑: Optimize multicast traffic delivery to relevant devices.
• 루프 감지: 브로드캐스트 스톰과 네트워크 불안정을 일으킬 수 있는 네트워크 루프를 방지합니다.

5.3 Network Connectivity Examp레

The QSW-L3208-2C6T-US supports various high-speed network configurations, suitable for connecting devices like PCs, Network Attached Storage (NAS), and media hubs.

6. 유지관리

6.1 펌웨어 업데이트

Regularly check the QNAP website for the latest firmware updates. Updating the firmware can improve performance, add new features, and resolve potential issues. Follow the instructions provided on the QNAP support page for the update process.

6.2 청소

To ensure optimal performance and longevity, keep the switch clean. Use a soft, dry cloth to wipe the exterior. Avoid using liquid cleaners or aerosols directly on the device.

6.3 환경 고려 사항

The switch is designed with a durable metal casing for effective heat dissipation. Ensure the operating environment allows for proper airflow to prevent overheating, especially in enclosed spaces.

7. 문제 해결

7.1 일반적인 문제 및 해결 방법

• 전원 없음: Check the power cord connection and the power outlet. Ensure the power adapter is securely connected to the switch.
• 링크 표시등 없음: Verify that the Ethernet or fiber optic cable is securely connected at both ends. Ensure the connected device is powered on and functioning correctly. Try a different cable or port.
• 네트워크 속도가 느립니다: Confirm that all connected devices and cables support the desired speed (e.g., 10GbE). Check for network congestion or duplex mismatch settings in the QSS interface.
• 접근할 수 없습니다 Web 사용자 인터페이스: Ensure your computer's IP address is in the same subnet as the switch. Verify the switch's IP address and try resetting the switch to factory defaults if necessary (refer to the installation guide for reset procedures).

7.2 루프 감지

The switch features loop detection to prevent network loops. A network loop occurs when there are redundant paths between network devices, which can cause broadcast storms and bring down the network. If a loop is detected, the switch will indicate this (e.g., via an LED indicator or QSS alert) and may temporarily disable the affected port to prevent network disruption.
