Title: Is my S17+ PSU toast? Post by: laborer75 on August 03, 2021, 01:30:18 AM I have an S17+ that will power up and all fans work on both the PSU and the miner. It will get me to the antminer interface. No hash boards show up at all. When I measure the voltage at the buss bars that connect to the PSU and the hash boards, I get no voltage. I tried another controller and get the same thing, no voltage between the two big buss bars. Shouldn't I be getting 14-21V at those bars?

If there is no voltage when checking it from Multimeter it means you have a defective PSU. Much better if you can post the whole kernel logs here you can find it on WebGUI. Don't forget to use the # button and paste the kernel logs inside the code before you post it here or you can use pastebin.com and paste the link here. Title: Re: Is my S17+ PSU toast?

Not really, if there is no load-demand the PSU will only be outputting 12V to supply the control board which powers the fans, but that doesn't mean your PSU is good, it's likely dead if all 3 hash boards stopped showing, maybe post some screenshots and the kernel log as they usually give enough information to diagnose the miner's issues.

I been mining with FPGA's so the BTC miners are a bit new to me. Ended up being a firmware problem. Thanks for the replies. :)
