Thanks for the help- But due to the fact the miner keeps shutting off and restarting that's all of the logs I can retrieve. I'm guessing maybe the psu is toast? TIA Best, J 
Do you have a multitester? Try to check the voltage value from the PSU(it must be 12V power) if it shows no or low voltage then your PSU is broken.
If you don't have a multitester then try this method below and it might be just a software issue.
- First, run the miner and then hold the IPreporter button for 15 sec then release. It should be restored to the factory settings.
Now, setup the miner with pools then test it again. Let's see if there are changes in the kernel logs after doing this.
- Try to upgrade it latest version available from Bitmain(Take note it can disable the SSH access)
- Refresh the miner by flashing it through an SD card with the SD card program recovery image.
But it's not available yet on Bitmain. Try to contact Bitmain and maybe they can give you the SD card program recovery for this unit or try to contact taserz he might have an s15 SD card image.
If these don't work you might have a broken PSU.
