EDIT:

That was on the Avalon 6 firmware. Funny enough, the A741 image, I don't get that at all. With just the AUC hooked up, I don't see anything about it in the Avalon section.

Same thing, A7 firmware:



However, in my miners, I can clearly see them (and they're powered on). So I'd say the A7 firmware won't show just the AUC unless its hooked up to a miner that's powered on.

----Only on Avalon 6 firmware:----

Ok, so it does look like the AUCs show up without power to the miner.


Here is what my control panel looks like with just the AUC connected to the Pi:



(Note: I have two AUCs, one is the newer one from an A741 and one is from an A6, connected to this Pi)

So you should at least see the AUC, even if you don't have the right power for the miner.
