Overview
This article lists the most common reasons that a NAS won’t power on or boot. Use this article to troubleshoot your NAS and find a solution.
Solution
Initial steps
By following these initial steps, you can potentially see if the problem is caused by something installed/added to the NAS.
- Power off your NAS.
- Remove all the drives, including M.2 SSDs.
- Remove any connected PCIe cards.
- Disconnect all USB devices from the NAS.
- If you have upgraded/changed the RAM, reinstall the original QNAP RAM modules.
- Power on the NAS.
Problem #1: The NAS does not power on.
Possible cause: Faulty power adapter or power supply
Check if the LEDs on the front panel turn on after pressing the power button.If none of the LEDs turn on, the power adapter or power supply of your NAS may be faulty. You can try plugging in the NAS to another power outlet to double-check.
Solution: Contact our Service Portal or your QNAP reseller for warranty repair service. For out-of-warranty units, a replacement power adapter/power supply can be purchased from the QNAP accessories store.
Problem #2: The NAS does not pass the POST (Power-On Self-Test).
Does the NAS produce a short beep about 5 to 10 seconds after being powered on? If not, the system has failed to pass the POST. The most common causes of this are a faulty motherboard or faulty RAM.
Solution: Contact our Service Portal or your QNAP reseller for warranty repair service.
Problem #3: Corrupted firmware image
Within five minutes after powering on your NAS, you should hear a long beep (about 1.5 seconds long). This indicates that the QTS operating system has finished booting.
The absence of a long beep may indicate that your NAS has corrupted firmware. This results in the NAS being unable to boot QTS.
This could be caused by the NAS being abruptly powered off during a firmware update.
Solution: Follow the firmware recovery procedure that is documented step-by-step in this guide. If recovering the firmware does not solve the issue, contact our Service Portal for assistance.
Problem #4: Non-hardware issue
If you experience none of the first three problems, and you hear a long beep after five minutes, then your NAS hardware has booted successfully. However, if you still cannot access QTS when booting with disks inside the NAS, then there may be a QTS system partition error or configuration file error on the disks.

概述
本文列出了 NAS 无法开机或启动的较常见原因。使用本文来排查您的 NAS 问题并找到解决方案。
解决方案
初始步骤
通过遵循这些初始步骤，您可以初步判断问题是否由安装 / 添加到 NAS 的某些东西引起。
- 关闭您的 NAS 电源。
- 移除所有硬盘，包括 M.2 SSD。
- 移除所有已连接的 PCIe 卡。
- 断开所有 USB 设备与 NAS 的连接。
- 如果您升级 / 更换了内存，请重新安装原装 QNAP 内存模块。
- 开启 NAS 电源。
问题 1：NAS 无法开机。
可能原因：电源适配器或电源故障
检查按下电源按钮后前面板上的 LED 灯是否亮起。如果没有 LED 灯亮起，您的 NAS 的电源适配器或电源可能有故障。您可以尝试将 NAS 插入另一个电源插座以再次确认。
解决方案：联系我们的服务门户或您的 QNAP 经销商以获取保修维修服务。对于不在保修期内的设备，可以从QNAP 配件商店购买替换电源适配器 / 电源。
问题 2：NAS 未通过 POST（开机自检）。
NAS 在开机后约 5 到 10 秒是否发出短鸣声？如果没有，系统未能通过 POST。较常见的原因是主板故障或内存故障。
解决方案：请联系我们的服务门户或您的 QNAP 经销商以获取保修维修服务。
问题 #3：损坏的固件映像
在启动 NAS 后的五分钟内，您应该听到一声长鸣（约 1.5 秒）。这表示 QTS 操作系统已完成启动。
如果没有听到长鸣，可能表示您的 NAS 的固件已损坏。这导致 NAS 无法启动 QTS。
这可能是由于在固件更新期间 NAS 突然断电造成的。
解决方案：请按照本指南中记录的逐步固件恢复程序进行操作。如果恢复固件不能解决问题，请联系我们的服务门户以获取帮助。
问题 #4：非硬件问题
如果您没有遇到前三个问题，并且在五分钟后听到长鸣声，则表示您的 NAS 硬件已成功启动。但是，如果在 NAS 内有硬盘的情况下启动仍无法访问 QTS，则可能是硬盘上的 QTS 系统分区错误或配置文件错误。
解决方案：请联系我们的服务门户以获取进一步的帮助和故障排除建议
