I currently don't have any HID UPS by hand to verify, but I'd be
surprised if they would advertise remote wakeup capability ... ?
Looks like mine does..

Remote Wakeup
I have reports of APC UPS remote wakeup working properly on "recent"
PowerMac G5s running OS X, but was never able to duplicate that success
on my cruddy old G3. I never figured out if it was a deficiency of the
UPS, the G3, or the OS. So it is possible that with appropriate OS
support this feature may actually work on certain UPSes (APC has a habit
of messing up the firmware differently on each model, so it's likely
hit-or-miss, but they are improving).
