so pull the unit and debug it at a bench. this has been the traditional method of working on large scale cluster deployments for decades, why do it any differently for mining? Commie's example is the ideal way of running a large group of mining rigs.
because pulling the unit with two PSU and (insert the number of GPUs) is a job for two people hehe.
besides pulling out and putting back in is a waste of time. look at what i said above, i fixed my hanging rig faster than you can pull that bar bell from a rack LOL.
Wrong. Hint: rails. It has rails.
Then it's just a matter of few screws and top cover.So you pull it out like a drawer. Then screws? Screw that. It maybe lighter with rails but it is a waste of time.
How about a rack with rails? You pull the whole rack to troubleshoot and push it back to the air pathway(vent)
A rack with rails is better than a drawer with rails hehe
