Mining gears are not like Pentium or AMD or xion servers, they do need baby sitting to make sure they run at optimum condition and time to time, you have to power cycle.  When you see sign of problems, fix them and intervene before further damages are done!!!

If you travel a lot, and want to make sure your mining operation at home is taking place, may want to have some webcam, networkable smoke detectors (heat sensors) and networkable PDU and VPN to access your miner's web control panel for the safe operation!
