I have this problem minute 1:37
https://www.youtube.com/watch?v=EATxCQRtgv0When I give a small shake to the antminer d3 it is as if the cards inside move, not much per se and it sounds as if the aluminum collide with each other, it happens to me like the video, please someone who knows the subject that can review it and give me some advice, if this is normal or I have to report it with bitmain, or if the miner can work normally despite this.
Thanks for your help.
