How can i get the Installer Password reset to the default paasword on a Comial JO816?

That is not an easy thing. If the grey KSU I think you can short capacitor and will reset to default but I am not sure if my memory is correct on that. There is a factory backdoor password you can use with laptop but do not think anyone will give it too you. Maybe just buy a refurbished one and be done with it

Thanks for the reply. No way for someone to do it from a remote location?

Only if you have a remote maintenance modem installed.
