Hi,
everybody loves happy ends ...
I tried to follow the lines of the data cable to get an idea what the purpose of the pins is. I didn't figure out so much, except for the Red-Line (Pin 2) is GND.
However, I where I am looking around, I thought: Ok, figuring out the IPMI Password may be taked 3-4 years, lets try the GND line to check if that helps.
So I connected everything again and plugged in the power connection and it boots up!
But wait - I din't started poking around with the connector!
What I did was simply unplugging the SATA cables (which were not connected to any harddrive anyway) and removing the datacable from the little daughter board which is basically a physical adapter to the back plane.
What I saw on the VGA is "SUPERMICRO" and System initializing. At the bottom right, there was this Status "1". However, it stays there.
I removed the power, waited at least a minute (That was a hint from the supermicro support) and tried it again.
Again just the Boot-Up Logo, but hey! At least something
...
Then: smoke!
I have basically no idea why that happened! I double checked the power connections: All fine ( +12V and +5Vsb), No circuit shortages ...
So ... there is the little guy how gone smoke ...
:-(
Update: Macro-Shot of it:
