Default password for GS1200-8v3

Hello,

I ve just a bought a brand new GS1200-8v3 and I try to authenticate to the management console. When I try to do so and enter the password specified in the user guide "1234" I am told the password is invalid. I tried other passwords like "0000" or "12345678" but all those passwords are wrong.

I did a reset on the switch… Still wrong. However the switch is supposed to be new and looks like it was never unpacked.

I am desperate. How is it possible that zyxel has messed up the every first step of the quick user guide of an easy tool like a switch ?
