Does anybody have experiences to integrate our APs with Juniper layer 2 switch(eg. EX2200) in the field?     Feild-proven already?  No Problem found?

We currently face an issue that some APs get rebooted with logs saynig "shutdown (ungraceful:unexpected cold restart)" quite rarely, and checking possible causes from many angles.

Your any input will be very help for us. We're using wing5.4.4
