Having a device drawing power before asserting link is normal - a
device has to draw power from the switch to energize the ethernet
circuitry that turns on the link.  With a working device though it
doesn't stay in that state for very long.  The power outage has
probably damaged your speaker.  If these are Atlas/Berbee IP speakers
I wouldn't be too surprised.  I haven't found them to be very robust.

unfairness of the universe."
