Why did my switch lose configuration/reset password after firmware upgrade?

Please be aware that for some switch models including but not limited to the GS1350, GS1900, GS1915, GS1920, etc., the configuration settings may not automatically be saved post-setup.

To ensure your settings are retained, it is crucial to manually save them. Once you have configured your switch, make sure to click on the 'Save' button, located at the top right corner of the management interface. This step guarantees that your modifications are preserved and persist across reboots.
