•Redundant power installation (2N load)—Four busways are powered from one power feed, and the remaining four busways are powered from a different power feed.

Drop boxes

The internal electrical busways provide a location to connect each of the drop boxes, which then power the PDUs. 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 enables load balancing with the rack equipment and is necessary to ensure redundancy.

•To disable power to a single rack, open the drop box breakers that power each of the PDUs installed in that rack.

•To disable power to a single busway, open the appropriate breaker for that busway on the corresponding electrical busway panel on the HP POD 40c G2 exterior.
