Hey

Did you try jacking into the controller via the 2nd LAN port?   That might let you into it directly via IP at which stage you can forget the switch then reset that way, manual IP on the connecting client is usually required.

I have had to do that before! 

  @Philbert Thanks but I actually have the opposite problem.  I have access to the controller.  The controller doesn't have access to the switch.  I can forget the switch, but the controller can't notify it of the change.

Here is the situation.

• There are no longer any ports on the default/management network
• As a result of the above there is no way to access the switch via IP
• There is no physical reset button on the switch
• There is no management port on the switch
• There is a console port, but there is no way to reset the switch once it is adopted
• I don't see any way to disconnect the switch from the controller in the console

So, basically, unless I am missing something, it is trivially easy to brick an Omada switch irreversibly.

If you can console onto the switch, try the Device Account username / password as par the controller (Settings / Site then at bottom).  

That might get you into the switch?!!   Here is hoping.. if not then I would call the Omada support and see what they say, generally found them very good for things like this.     Link below for tel numbers.   Just change to your local region as im UK

  @Philbert I can get into the switch via the console port.  I just can't make any changes.  Once the switch it adopted, you can't make changes via the console it seems.

I can read all the counters or clear them.  I can view the switch configuration, but everything else is restricted.

  @Alex789 

I would give the support line a ring mate, there has got to be a way around this one.

Thankfully i have been lucky enough to have controller access and only locked out the client ports!   Now ive said that of course it will happen on Monday :)

  @Somnus Thanks for that.
