Factory reset Problem on SX1036 Switch


We here have a Mellanox SX1036 Switch, which was found on eBay. Becaurse of the fact that we have one of those switches in our infrastructure, we bought this device as a cold spare.

The problem now is, that we have no password for this device - and also the factory reset does not work. If we press and hold the reset button for 10, 15, 30 or even 60 secs, the switch boots up and there is still the old host name and password. We`ve also booted another image via console but also this has no effect on login or resetting this switch.

What can we do now? The seller also does not have the admin- password.

Here is our startup-log:

We hope that anyone is able to help us.

Thank you in advance


Do you find a way to reset the password? I’m stuck at the same place with a SX6036… Thank!

I do find a way. use the xmladmin/xmladmin user/password to login and change the admin password.
