Drop boxes
The internal electrical busways provide a location to connect each of the drop boxes, which then power the
PDUs. For each IT section, stagger the drop boxes on the electrical busways by connecting one drop box to
PDUs. For each IT section, stagger the drop boxes on the electrical busways by connecting one drop box to
busway #1 and connecting the next drop box to busway #2. A staggered configuration allows for load
balancing with the rack equipment and is necessary to create redundancy.
