I'll gladly help where I can. I did reach out to their product support, and
I did not have install the displaylink driver as that is for a totally
different product, so ignore all that.
The 208 V makes sense. The unit spec designates it as a 208V input, and
from looking at what we have in the server room, the battery is a 48VDC
For outputs, this UPS has (12) 5-15/20R; (2) L6-20R; (2) L6-30R, but
according to the output that I posted, only 9 are detected.
I'm new to this, so let me know what you need from me and I will try my
best. This UPS does power our production servers, so shutting things down
aren't an easy task, but this weekend might open up some opportunity for
that if need be. If I need to test it by unplugging the main power, that I
can do without problems.
