To all, 
Recap of Service Call: 
Arrived on site and jumped on the bridge with Alexandra 
Located and unboxed the UPS replacement 
Realized that the Rack had the location is a Music Rack with smaller screws needed which I had brought Network Rack screws and those did not fit.  At this time, I do not have any more small screws to fit that Music Rack.   
Also, FYI, the UPS in itself is about 40 LB so it would require two people to hold it at the bottom of the Rack and properly secure it (the ears for that UPS have been installed) with the correct screws to fit into that Music Rack  
The old UPS was sitting on a site stand so I installed the new UPS on that stand next to the Music Rack (see picture)  
I disconnected all the equipment and reconnected the Network Switch, the Router, the Comcast Ciena, the Comcast Modem and the two music devices as well as the DVR.  All other equipment was connected to an extension cord    
Then Alexandra and I proceeded to test the network (Manager's PCs/Wifi/Toast equipment, etc) to make sure everything was back online.    
Took pictures for the report and left
