Got my 3 miners. Two of them had to be opened up to fix loose cables. One to the ethernet, and the other to the blade. After that the miners started working and are hashing away just under 1th for the last 2 hours. These ones had different subnet mask and gateway IPs that i had to set that were different than my first batch of dragons. Just in case anyone has issues, check those fields.
it seems like the loose cable is a main problem caused by long express trip. i will ask factory to find a solution to this problem, is there any suggestion from your guys, i know many of you are professional engineer
ESD-tape, problem solved.
