Best way to shut down an Avalon 741?

[timk225]

For the 741, there's 2 ways to shut it off - turn off the controller first or the main power supplies.

For mine, I figured that if I shut down the controller first, that would end the data stream and the miner would go to idle.  And it did, so I could then safely give it a few minutes to cool off before turning off both power supplies (HP server 1200 and 750 watt PSUs).

That's what I tend to do. It just seems to be the gentlest way to power down the equipment.

I actually run 2 741s on 2450w psus which is why I started thinking of a way to avoid just throwing the switch.

I tend to stop cgminer from the status page. Watch the miners idle until they are cooled down to the touch. Then throw power and disconnect.

After this if I have to move the controller I unplug it.
