Electrical busway

The electrical busway is a modular, overhead electrical distribution system that supplies power to the HP POD IT loads. There are two electrical busways in the standard HP POD (1 and 3) and three electrical busways in the high density HP POD (1, 2, and 3).

Each PDU is powered by the dropboxes attached to each of the electrical busways.
