I can't reset the switch because the embeded os don't start correctly...

I don't have see any "hidden" little button on the switch.

How can I reset my switch with factory configuration ???

Help, please !

Thank you in advance !

    Welcome to Zyxel community.

    GS2200-8  has a button at the right side panel, but the function is only to reboot the switch.

    Based on your current status, please refer to this link to resolve the event.

    Hope it helps.

    Hi @xungbv

    If you can not access debug mode of your device, it's probably a hardware issue.

    Please direct to your reseller for RMA.
