Symptom
After powering on the switch, QFinder Pro cannot detect the switch on the same local network.
Analysis
- By default, QNAP switches obtain an IP address via DHCP. If no DHCP server exists or the network has issues, the switch may not appear in QFinder Pro.
- A green and blinking status LED indicates the switch is booting. Booting should normally complete within 5 to 10 minutes. If the LED continues blinking, it may indicate a boot issue.
- If your computer was previously set to a static IP address to configure the switch, you may need to revert to automatic IP allocation to communicate on the same network.
Solution
- Check network connections:
- Ensure that the switch and your computer running QFinder Pro are connected to the same LAN.
- Verify all cables are securely plugged in and the network port LEDs are active.
- Verify your computer’s network settings:
- If you previously assigned your computer a static IP to access the switch, restore your original network settings. This ensures your computer is on the same subnet as the switch.
- Check DHCP server availability:
- QNAP switches use DHCP by default to get an IP address. Make sure a DHCP server is active on your network.
- If no DHCP server is available, the switch may not be assigned an IP address and can't be found by QFinder Pro.
- Try accessing the switch using a web browser:
- If you know the switch’s IP address, enter it in your web browser to access the management interface.
- If you do not know the IP address, check your DHCP server or router’s client/device list for a device labeled as QNAP switch.
- Restart the switch and your computer:
- Power cycle both the switch and your computer to refresh network connections.
- Reset the switch to factory defaults (if necessary):
- Warning: Resetting the switch erases all custom settings and restores factory defaults.
- To reset, press and hold the physical reset button for 10 seconds.
- After resetting, use QFinder Pro again to locate the switch and perform reconfiguration as needed.
If the status LED remains green and blinking for more than 10 minutes and the switch is still undetectable, you can use the console port to investigate further. For guidance, refer to How to use the console port to check system information on a managed switch. If needed, collect booting information and contact QNAP support for further assistance.

症状
开机后，Qfinder Pro 无法检测到同一局域网内的交换机。
分析
- 默认情况下，QNAP 交换机通过 DHCP 获取 IP 地址。如果没有 DHCP 服务器或网络出现问题，交换机可能不会出现在 Qfinder Pro 中。
- 绿色闪烁的状态 LED 表示交换机正在启动。启动通常应在 5 到 10 分钟内完成。如果 LED 持续闪烁，可能表示启动问题。
- 如果您的计算机之前设置为静态 IP 地址以配置交换机，您可能需要恢复为自动 IP 分配以在同一网络上通信。
解决方案
- 检查网络连接：
- 确保交换机和运行 Qfinder Pro 的计算机连接到同一局域网。
- 确认所有电缆已牢固插入且网络端口 LED 处于活动状态。
- 验证计算机的网络设置：
- 如果您之前为计算机分配了静态 IP 以访问交换机，请恢复原始网络设置。这确保您的计算机与交换机在同一子网中。
- 检查 DHCP 服务器的可用性：
- QNAP 交换机默认使用 DHCP 获取 IP 地址。确保网络上有活动的 DHCP 服务器。
- 如果没有 DHCP 服务器，交换机可能无法分配 IP 地址，Qfinder Pro 无法找到。
- 尝试使用网页浏览器访问交换机：
- 如果您知道交换机的 IP 地址，请在网页浏览器中输入以访问管理界面。
- 如果您不知道 IP 地址，请检查 DHCP 服务器或路由器的客户端 / 设备列表中是否有标记为 QNAP 交换机的设备。
- 重启交换机和计算机：
- 将交换机重置为出厂默认设置（如有必要）：
- 警告： 重置交换机将清除所有自定义设置并恢复出厂默认设置。
- 要重置，请按住物理重置按钮 10 秒钟。
- 重置后，再次使用 Qfinder Pro 定位交换机并根据需要进行重新配置。
如果状态 LED 保持绿色闪烁超过 10 分钟且交换机仍无法检测到，您可以使用控制台端口进行进一步调查。有关指导，请参阅如何使用控制台端口检查管理交换机上的系统信息。如有需要，收集启动信息并联系QNAP 支持以获取进一步帮助。
