[HamWAN PSDR] VOTE: $420 for a new Baldi UPS

[Bart Kus]

Yup, it's rackmount, although that's not the specific model.  The exact 
model is SU2200RTXL2U, it's spec'd out here: 
http://www.tripplite.com/shared/product-pages/en/SU2200RTXL2U.pdf . We 
won't be getting rails with it, which is OK, since Baldi doesn't have a 
rack that can mount it.  The existing UPS just sits on a bench in the cage.

Our balance should be sufficient to get this without needing to raise 
any funds, although I'd need someone from the board to step in and give 
exact details.
