... and what happens if you try issuing a "shutdown -h now" ?

That's not a problem as i'm there then. The real problem is when i'm asleep that the cheapo 12 volts adapter that runs fans of a precious Mellanox component, that it breaks.

I think the question is what happens if you let a script issue the "shutdown -h now" when the temperature gets too high?


Then the computer will shut down but not the switch. The switch has no button to turn off.

So the switch will melt, as i removed the internal fans from switch as those make 70+ decibel. An external computer i can have monitor those external fans and undertake action when it notices that they stop working or one of them.

So one solution is to have a legorobot equipped with a small hammer and have it hammer on a button, having the computer steer the legorobot, and turning off the switches power by hammering onto the button of the 240 volt power with the lego robot.

Big odds that hammering goes wrong.
