Hi @Classicm,

May I know which firmware version did you upgrade from and to?

Hi, thanks for the reply. I went from V1.6 to V2.7.

I have not changed the default admin login/password

Hi @Classicm,

Since GS1900-8HP doesn’t have V1.6 firmware, I assume you were using V2.60 firmware. So, I tried to reproduce this problem from V2.60(Patch1) to V2.70(Patch5), V2.60(Patch2) to V2.70(Patch5), V2.60(Patch3) to V2.70(Patch5), V2.60(Patch4) to V2.70(Patch5), but I can still use admin/1234 to log in.

To fix your problem, please press the reset/restore button in the front panel for 10 seconds to factory default it.
