Yes.

Please see below.

Hmm.. I don't think so? see below.

I removed all servers and workstation from the output of the ups.
I then connected my periphery (monitor, printer, soundsystem...) to the 
battery backed-up output of the ups to have some load. (maybe its only 
3%, but I it showed the same behaviour as with the servers attached)
After running the command, the ups went off. There was a "klick" :-)
My monitor went off. My Soundsystem went off. I then had to press the 
ups' power button to turn it back on. The ups has a load of about 55% 
when everything is running under heavy load.
