So far so good on my devices 

3 days ago and today i put them back to my ruckus switch 

When i put them on a new poe switch i lost connection for 3-4 times for the last 2 days today I haven’t lost my connection so far

Well, i just plugged them back to my icx7150 switch and so far so good could be just firmware

@young_joon_kwon not sure but still sometimes i lose connection , also i have 500mbps speed i get only 300 i did hard reset many times and i lost the license after i did it the 1st time don't know how to get it back
