they are HP R7000, made by Eaton.   4U 7KVA rackmount.   they need 208 
40A(?) service.  ethernet interface is standard.   They support up to 4 
extended runtime modules (4U each).   at 80% usage, HP claims 6 minutes 
with the base unit and 57 minutes with 4 ERM's (3U each).

These things are 165 lbs, they were a gut buster to load into the racks, 
heh.  after the 1st one, I removed the batteries from the other 3, and 
it was way easier.   They use 18 12V 45W UPS batteries, in two packs of 
9 each.

I don't remember the price we paid, we bought these last year, but we 
get a substantial discount on HP gear.   google suggests $4500 at
