Are you powering *only the E4B or also other rack features?
Additional drives in a separate rack component?
Rack comm equip?
Have a building generator & how long till kicks in?
If no generator, how long do you require? 5 minutes or 5 hours..

Note that now many rack UPS's are 208/240 (US) and don't come with 120v plugs... takes an additional component ($$) if you have older equipment or console is a standard pc.
Lot's to consider.
