I want to power off an Antminer D3.

I have read online that the best way to do it is by connecting via ssh and executing poweroff.

However, I cannot login from my Mac to the miner with ssh -p 22 root@192.168.0.xxx or ssh root@192.168.0.xxx.

It does not accept the default password "root":

Permission denied, please try again.

How can I log in and do I really have to shut down the miner this way? It makes sense to not turn off the fans immediately by unplugging the PSU.

Default password admin for user root worked.

  • They don’t really stop mining if you shut it down. – Anonymous Dec 6 '17 at 4:08
  • @eponymous why don’t they stop mining? What is shutting down then? – Manuel Dec 6 '17 at 12:31

    You can turn off the control CPU but the mining chips are always connected to the power. I was imagining you were trying to schedule it’s usage. – Anonymous Dec 6 '17 at 13:01
  • @eponymous I intended to gracefully shut the miner down where the fans would still run some time after it stopped mining, so the chips don’t overheat. – Manuel Dec 6 '17 at 13:03

    They’re designed for extremely high heat operation, there’s no danger in just unplugging it. It will probably happier with continuous operating rather than heating and cooling cycles. – Anonymous Dec 6 '17 at 13:04
