R510 has no power

[vchekkilla]

Using Ruckus ICX 7150-C12P with three Access Points (R510) for the last five years. Suddenly yesterday all three access points stopped working. Ruckus 7150 is getting power and has an internet connection but R510 does not have any connectivity, it is using POE as power input.
Also, my Unleashed account is not accessible. I did forget the Unleashed password which did set up and tried the default ones that are not working too, could you advise which one I can use?
Followed these steps but had no luck.
- Did the "HARD RESET" and tried to log in through a web browser using its default IP address 192.168.0.1 but it was not allowed.
- Tried to reset APs and it has no power connectivity also.

On Ruckus switch (ICX 7150-C12P) I can see two green lights, able to connect to internet using ethernet cable from switch.

Would like your team's help to fix my APs issue and make them work.
