I found this post that has the same issue. I followed the step by step guidance. https://community.ruckuswireless.com/t5/RUCKUS-Support-for-Lennar-Homes/Power-Outage-caused-issue-with-switch-access-points-not-working/td-p/70336
First the syst light is yellow and PWR light is green (rest of the light are off) and the access point is not power up.
I try to reset the swith by turn off the power, use a pin to press the reset button, and turn the power back on. Now all the lights are flashing yellow except the PWR is green. The first time I wait about 10 minutes, and the flashing is never stop. I turn off the power and turn back on, back to the first step syst light is yellow and PWR light is green. I tried again to reset the swith, now the lights are flashing about half hour and never stop.
What else I can do? Can you replace the switch for free?
