Makes some sense.  If the AUI port is used, it needs 12V.
It if isn't used, it doesn't.

When Apple wanted to use AUI ports, but didn't have 12V, they designed
AAUI.  (That is Apple AUI) which uses a different connector and 5V instead
of 12V. 

Some have a switch to turn on/off the AUI port.  Some sense the current load
and turn it on.

I had one device that generated very bad smelling smoke.
That is, the phenolic smell that many recognize as burning
electronics, and others as hospitals. 

I put it in a sealed plastic bag.
