Since Bitmain delayed the launch by about a week, and there are some speculations around the number of first batch units, it would be interesting to see what the demand looks like. 

I can't seem to make sense of the LEDs on the controller board. Does anyone have a cheat sheet that shows what each led means?

The one I am interesting in is the one right under the rj45 Ethernet connector.  I think most miners will have both of them lit.  Like this:



However, on just one of my S1 miners, only the left one (under the Ethernet connector, furthest away from fan) is lit, the right one is off. 

Any ideas?  It is working fine, just want to understand what it indicates.

Thanks
