Yeah, I'd just need to know what kind of batteries. If the things ran on
48VDC I know how to make that work with my telecom 48VDC setup, assuming they
don't mind the positive ground. If 60VDC I can take the necessary 5 12V
12-270's out of the Controlled Power beast easily enough.

Yes, it is. See www.pari.edu for better shots than what you'll find on Google
Earth; the GoogleEarth detail is cut back badly. Terraserver has good
visuals, though.

Freight on the 120V APC SmartUPS 3000RM5U's that I have was a little over $100
each, Old Dominion, batteries included. I got them on eBay for $225 each;
got a grant that covered new battery packs, and have five good working units
(out of six purchased). Wish I had the twin 225KVA units the site's previous
occupants took with them...or the 600V 1320Ah battery bank to bring the
500KVA Piller back up....at least they left the three 125KVA Leibert PDU's.
I'm going to make the attempt to power the 3006 up tomorrow (I have
maintenance windows on Saturdays); we'll see what comes of things then.
