Is it safe to shutdown Antminer daily?

[thephoenixxp]

Hi,

I'm the recent owner of an Antminer D3 rig. Since the miner is pretty loud, I would like to set it up so it automatically shuts off every day, for a few hours. If I issue the shutdown -h command via ssh and then, after a few minutes, unplug it (I've noticed the fans never stop, even if it's powered off), can this be harmful in any way for the miner, on the long term? Are there any power-on cycles I need to consider for it or its hard-disk, memory etc.?


Thanks!

There's no problem in the longrun if you do it correctly - you should shut down mining on the device ~5 minutes before you're going to turn it off, this way you won't cause thermal shock (you'll know the right time period, it should just be blowing air out the exhaust that's basically the same temp as the intake).  Then just power down the rig with a PDU or remote power switch of some sort.
