According to the manual you can do a cold reset by holding the reset button in for 3 seconds. This does seem to reset it but the username and password are not reset...

I've tried the keyboard hotkeys - Num-Lock and minus sign (-) to get into hotkey mode and then use the "r" and "" to reset to factory defaults but that doesnt seem to do anything either. It just reverts to User1.

I'm not sure what the default admin username should be but admin doesnt seem to work

I need to get to the admin menu to name the ports but cannot get access. Any ideas?

Using GCS1758 manual with no luck.
