anyone use force 300 with mikrotik PowerBox Pro or any hex poe Gigabit at 1 gbps?

i try to undestand a problem specifically with the two... Just to verify a theorie... When i used force 300 with powerbox pro i got under a lot of instability like all port from the powerbox pro disconnect and reconnect and i can say a got this problem from two site... i got more stability at 100 mbps but got reboot problem from 1 or 2 time a day... it's start to make me crazy... I change the cable ,Routerboard ,Power supply and the Radio... 

Try this post regarding pause frames, see if it helps… basically looks like try latest Mikrotik firmware plus beta cambium firmware…
