Overview
After a sudden power outage or voltage surge, your NAS may no longer be visible in Qfinder Pro, or accessible via the web interface, or bootable.
Possible symptoms may include:
- No LED activity or beep sounds during startup
- LEDs appear normal, but NAS is not reachable via LAN
- Drive LEDs blink abnormally or not at all
- NAS powers on but fails to complete boot
Root Cause
A QNAP NAS may fail to boot after an unexpected power loss due to:
- Corrupted internal firmware (DOM/Flash): If the firmware was being accessed or updated when power was lost, it may be damaged.
- Unstable or faulty drives: Drives with critical errors may prevent the NAS from completing system initialization.
- Interrupted firmware upgrade: If a power failure occurred during a firmware update, the system bootloader or OS may be incomplete.
- Network misconfiguration: DHCP or IP resets may result in the NAS not being reachable.
Solution
Step 1: Boot the NAS without any drives
- Power off the NAS.
- Remove all hard drives from the NAS.
- Power on the NAS without any drives inserted.
- If the NAS boots and you hear the beep: This confirms that the system firmware and hardware are working. Proceed to Step 2.
- If the NAS still does not boot: The issue could be a corrupted DOM or mainboard failure. Refer to the NAS Recovery Guide or contact QNAP Technical Support.
Step 2: Test the hard drives
- If the NAS boots without drives, the issue is likely related to the drives.
- Identify any drives previously flagged with SMART errors, abnormal noises, or system logs.
- Insert a drive that you believe is healthy and power on the NAS.
- Insert another drive and test again.
- Continue until you identify the drive (or multiple drives) that prevents successful boot.
Step 3: Restore system access
If the NAS boots successfully:
- Connect the NAS and your computer to the same subnet.
- Use Qfinder Pro to locate the NAS on your network.
- If the NAS is still not visible:
- Try a direct Ethernet connection with static IP address (e.g., NAS: 192.168.1.100 / PC: 192.168.1.101).
- Reset the NAS network settings by pressing and holding the reset button for 3 seconds. This only resets the admin password and IP settings.
- Do not perform a 10-second reset unless you understand its full impact.

概述
在突然断电或电压波动后，您的NAS可能在Qfinder Pro中不可见，无法通过网页界面访问，或无法启动。
可能的症状包括：
- 启动时没有LED活动或蜂鸣声
- LED显示正常，但NAS无法通过局域网访问
- 硬盘LED异常闪烁或完全不闪烁
- NAS开机但无法完成启动
根本原因
由于以下原因，QNAP NAS可能在意外断电后无法启动：
- 内部固件损坏（DOM/Flash）：如果在断电时正在访问或更新固件，可能会损坏。
- 不稳定或故障的硬盘：有严重错误的硬盘可能会阻止NAS完成系统初始化。
- 固件升级中断：如果在固件更新期间发生电源故障，系统引导程序或操作系统可能不完整。
- 网络配置错误：DHCP或IP重置可能导致NAS无法访问。
解决方案
步骤1：在没有硬盘的情况下启动NAS
- 关闭NAS电源。
- 从NAS中移除所有硬盘。
- 在没有插入任何硬盘的情况下启动NAS。
- 如果NAS启动并听到蜂鸣声：这确认系统固件和硬件正常工作。继续执行步骤2。
- 如果NAS仍然无法启动：问题可能是DOM损坏或主板故障。请参考NAS恢复指南或联系QNAP技术支持。
步骤2：测试硬盘
- 如果NAS在没有硬盘的情况下启动，问题可能与硬盘有关。
- 识别任何之前标记为SMART错误、异常噪音或系统日志的硬盘。
- 插入您认为健康的硬盘并启动NAS。
- 插入另一个硬盘并再次测试。
- 继续直到识别出阻止成功启动的硬盘（或多个硬盘）。
步骤3：恢复系统访问
如果NAS成功启动：
- 将NAS和您的计算机连接到同一子网。
- 使用Qfinder Pro在您的网络中定位NAS。
- 如果NAS仍然不可见：
- 尝试使用静态IP地址进行直接以太网连接（例如，NAS：192.168.1.100 / PC：192.168.1.101）。
- 通过按住重置按钮3秒钟来重置NAS网络设置。这只会重置admin密码和IP设置。
- 不要执行10秒重置，除非您了解其全部影响。
