Good point about the redish LED. I didn't think about that. I will take a picture and add it into the guide.
For your PSU wise, are you using the yellow +12V line from the 4pin molex (SATA/IDE) cable? If so, don't do that, it will heat up quite a bit. (Most molex cable can support 60-80W but the miner needs at least 180W on one side)
If the main PCI ATX or PCI-E +12V lines are getting to the point you can't touch, you may want to check if your PSU is strong enough to support it, or if there is too much resistance on the line for whatever the reasons. The lines from the AntMiner I'm running doesn't get hot at all and it's on the 450W PSU with +12V from PCI-E and PCI ATX lines. (1 Line I double up the cable for both Yellow and Black just to be sure/safe because I want to let it run without attending the unit everyday.)
Everything seems to work fine the way you describe. I put the 3 cables on the blade with the control board and the other 2 on the second. The miner runs fine and it hashes as advertised (180GH/s). The power cables are a bit hot to the touch, but not extremely. I'll monitor more closely for the first days, but I guess this is expected.
Thanks for your guide, it was very helpful. I was a bit surprised by the red led at first, but since everything is running fine I guess it is normal. Maybe it's worth mentioning in the guide...
