1. what is access like; are there any stairs or obstacles that we have to maneuver?

The UPS is located in Room 102A on the main floor; no stairs (see attached schematic). No permanent obstacles exist. Room 102A has ample space for installation. The reception desk that sits outside of the room allows 36" of width clearance to the room. The current components (2) measure 31"D x 27" W x 71"H and 31x31x71, respectively.
