My NAS doesn't power on or boot. How can I fix this?

Applicable Products:

• All NAS series

  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.

Initial steps

By following these initial steps, you can potentially see if the problem is caused by something installed/added to the NAS.

1. Power off your NAS.
2. Remove all the drives, including M.2 SSDs.
3. Remove any connected PCIe cards.
4. Disconnect all USB devices from the NAS.
5. If you have upgraded/changed the RAM, reinstall the original QNAP RAM modules.
6. Power on the NAS.

Problems, Causes, and Solutions

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.
