How to reset your Synology NAS

Overview

Every Synology NAS server comes with a RESET button. There are two different reset modes: The first mode allows you to reset the administrator password and network settings; the second mode allows you to reinstall the operating system (this also resets the administrator password and network settings). Both methods make use of the RESET button. This article will guide you through the necessary steps.

This section will guide you through the necessary steps to reset the administrator password and network settings. After resetting your Synology NAS, your system configuration will result in:

  • To restore admin account to default value.
  • To reset the UI management port to 5000/5001.

Note: The RESET performs various functions on different versions of DSM. This FAQ explains in further detail. Before proceeding to reset your Synology NAS to factory default settings, you may also want to back up your current configuration. For detailed instructions, please see this tutorial.

To reset the administrator password and network settings:

  2. Note: If you have difficulty locating the RESET button, please refer to the Quick Installation Guide for your model here.
  3. Using a paper clip, gently press and hold down the RESET button for about 4 seconds until your Synology NAS emits a beep sound. Release immediately.
  4. Warning: Pressing the RESET button continuously will cause the operating system to reinstall.
  5. Launch Synology Assistant and double-click your Synology NAS to login. At the login page use “admin” as the user name and leave the password field blank. You can now reconfigure the administrator password and other network settings.
  6. Note: This procedure is only applicable when DSM is installed. If DSM is not installed, nothing will happen; however, the system will still beep. See the next section for how to reinstall DSM.
