4. 설정

Follow these steps to set up your QNAP QSW-L3205-1C4T-US network switch.

4.1 물리적 설치

1. 놓기: Choose a stable, flat surface or a suitable location for wall mounting. Ensure adequate ventilation around the switch.
2. Attach Rubber Feet (Optional): If placing on a flat surface, attach the included rubber feet to the bottom of the switch to prevent slipping and provide minor elevation for airflow.
3. 전원 연결: Connect the power cord to the power adapter, and then plug the adapter into the DC power input on the rear panel of the switch. Plug the other end of the power cord into a power outlet. The Power LED on the front panel should illuminate.

4.2 네트워크 연결

1. 장치 연결: Use standard Ethernet cables (Cat 6a or higher recommended for 10GbE) to connect your network devices (e.g., computers, NAS, servers, routers) to the RJ45 ports (1-4) on the front panel.
2. SFP+ / RJ45 Combo Port: For fiber optic connections, insert a compatible SFP+ transceiver into the combo port (Port 5) and connect a fiber optic cable. Alternatively, for an additional RJ45 connection, use an Ethernet cable in the RJ45 part of the combo port. Note that only one type of connection can be active on this port at a time.
3. 연결 확인: Once devices are connected, observe the Link/Activity LEDs for each port. A solid green or amber light indicates a successful link, and a blinking light indicates data activity.

5. 사용 설명서

The QSW-L3205-1C4T-US is a Lite-Managed switch, offering a balance of plug-and-play simplicity with essential management features. For basic operation, simply connect your devices, and the switch will automatically negotiate the optimal speed.

5.1 Automatic Speed Negotiation

Each RJ45 port on the switch supports auto-negotiation for 10G, 5G, 2.5G, 1G, and 100M speeds. The switch will automatically detect the speed of the connected device and adjust accordingly. The Speed LEDs will indicate the current connection speed.

5.2 Accessing Lite Management Features

For advanced configuration and monitoring, use the QNAP Switch System (QSS) web interface or Qfinder Pro utility. Refer to the QNAP website for the latest QSS user manual and Qfinder Pro download.

6. Lite Management Features

The QSW-L3205-1C4T-US provides several lite management features to optimize your network.

6.1 링크 집계(LACP)

LACP allows you to combine multiple physical links into a single logical link, increasing bandwidth and providing redundancy. This is particularly useful for connecting to NAS devices or servers that require higher throughput than a single 10GbE connection can provide.

6.2 VLAN Segmentation

Virtual Local Area Networks (VLANs) allow you to logically segment your network into smaller broadcast domains. This can improve network security, reduce broadcast traffic, and enhance overall network efficiency by isolating different departments or types of traffic.

6.3 서비스 품질(QoS)

QoS features (CoS / DSCP) enable you to prioritize network traffic. This ensures that critical applications, such as VoIP, video streaming, or data backups, receive sufficient bandwidth and experience minimal latency, even during periods of high network utilization.

6.4 Traffic Monitoring

The QSS interface provides tools for monitoring network traffic, allowing you to view real-time data usage per port. This helps in identifying bandwidth bottlenecks and troubleshooting network performance issues.

6.5 펌웨어 업데이트

Regular firmware updates are crucial for maintaining security and optimal performance. The QSS and Qfinder Pro utilities allow for one-click firmware updates, simplifying the process and keeping your system secure and up-to-date.

• 콘센트 확인: 다른 기기를 사용하여 전원 콘센트가 정상적으로 작동하는지 확인하십시오.
• 전원 어댑터: Ensure the power adapter is correctly connected to the switch.

8.2 No Link/Activity LED

• 케이블 확인: 이더넷 케이블이 스위치 포트와 연결된 장치에 제대로 연결되어 있는지 확인하십시오. 다른 케이블을 사용해 보십시오.
• 장치 상태 : Verify that the connected device is powered on and its network adapter is functioning correctly.
• 포트 호환성: Ensure the connected device's network adapter supports the speeds offered by the switch ports (10G/5G/2.5G/1G/100M).
• SFP+ 모듈: If using the SFP+ combo port, ensure the SFP+ transceiver is correctly inserted and compatible.

8.3 느린 네트워크 속도

• 케이블 품질: For Multi-Gigabit speeds, use Cat 6a or higher Ethernet cables. Lower category cables may limit performance.
• 장치 기능: Ensure all connected devices and their network adapters support the desired Multi-Gigabit speeds.
• 교통량 모니터링: Use QSS to monitor port traffic and identify any heavily utilized ports or devices.
• 펌웨어: Ensure the switch has the latest firmware installed.

8.4 Network Loop Detected (Loop LED On)

• Identify Loop: A network loop occurs when there are redundant paths between network devices, causing broadcast storms. Disconnect devices one by one to identify the source of the loop.
• 케이블 구성: Review your network cabling to ensure there are no unintended loops.
• 스패닝 트리 프로토콜(STP): If configured, ensure STP is enabled and functioning correctly to prevent loops.
