Busway drop box

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.

IMPORTANT: HP recommends that you shut down the associated IT equipment and de-energize the appropriate section of the power busway before attempting to remove or replace a busway drop box. The corresponding branch circuit breaker is labeled on the busway.

You need a socket wrench to remove and replace the busway drop box.

Removing the busway drop box
