S19J & S19a ERROR_POWER_LOST: get power type version - PSU Version A vs Version C

Hello - 

I have an S19J and two S19a who had PSU fail after one day of operation.  Bitmain didn't honor their warranty and told me it was my problem.  So here I am a month after sending them to Bitmain, I gave up debating who should pay for the PSU and purchased three brand new Bitmain PSU to replace the defective units.  The issue I am having is that once I installed these new PSU, the controller boots up, but it won't hash.  In the Kernel Log, I get "ERROR_POWER_LOST: get power type version" and then it shuts down hashing.

HOWEVER, when I pull a working PSU from another S19a or S19J in the group of miners I purchased with these defective miners, these 3 miners fire right up and hash as expected!  The only difference I can figure is that the APW12 PSU on the miners are "Version A" and the replacement branded Bitmain PSU are "Version C".  Any advice on getting these PSU to work?

Thanks, Ben

  Hi Ben, we'll need the kernel log for further check, you can contact us at support-cs@bitmain.com to provide it.
