I have a large project that requires some temporary gateways. I purchased 4 used QX E1/T1 hoping they would get me through the cutovers, with new QX E1/T1 replacing them long term. Of the 4, three Quadro E1/T1 units after factory reset, the default username and password doesn't work. The fourth one works great. They originally had different IP addresses, and after a physical reset it is back to So I know they have physically reset.

I"m wondering if older firmware maybe had a different default IP address? or if there is a known bug with resetting these particular devices. Or maybe they are just bad and this is one of the failures that are experienced.

Unfortunately, I don't know what firmware version they are running.

Model - sasy-soho-0102-0300

Any suggestions would be appreciated.
