Per UL requirements, almost all transformer style power bricks will
incorporate a (non field replaceable) fuse. If you short the output, the
fuse pops.

Subject: [AFMUG] Cat5/6 POE splicing while live?
Is it possible to cut into a POE injected Cat5/6 run without frying stuff?
I think I've done it on regular Ethernet without causing damage to the
Ethernet port, but maybe I'm pushing it with that too?
I know the safest way is to unplug the Ethernet cable, then do the
splice/work/end on it, then plug it back in, but would be really nice if I
didn't have to bother the home owner when fixing/splicing a live run to
the outside of the house.
