Greetings of the day,
Based on your description, the issue may be due to after the blackout of the switch began to run routing. We can know it with this indication SPR08090d that R it means Routing code , basically we have to change the code to switching back.
Here I share the basic credentials to access the switch and also to access to the unleashed dashboard.
User: admin Password: Lennar
User: admin Password: Ruckus!
user: super Password: sp-admin
User: admin Password: password
User: admin Password: admin
User: admin Password: sp-admin
User: admin Password: Ruckus1
User: admin Password: ruckus
Please find the below password recovery video:
Another option will be in the OS mode to try to force the device to boot up from the primary image
Boot from 0->reload, 1->primary, 2->secondary
If you can have access to the switch you can run the following commands in order to prevent this issue in the future
ICX7150-24P Router> ena
ICX7150-24P Router# show flash
Most of the Lennar homes has the switching code in the primary image (SPS08090d) with the following command we are going to remove the routing code image in to the secondary in order to avoid this issue if there is any power outage in the future
ICX7150-24P Router# copy flash flash secondary
