Re-adoption of old T1500G-8T v2.0 fails
I used to manage two old T1500G-8T v2.0 switches via Omada Software controller. And although they are not listed as supported devices any more, it was still working. Now, I needed to reconfigure one of those switches. Therefore, I forgot it in Omada and reset the switch to factory defaults.
Switch and controller can still ping each other but the switch doesn't appear in the list any more, not even as pending.
Is this because of the switch is officially not supported any more? Why is the other one still working fine then?
Would it be possible to downgrade the controller to readopt the old switch and then upgrade back again?
Thanks for any recommendation.
