A rack can have one, two, or three pairs of PDUs. In each pair, one PDU is installed on the left side of the rack. The other PDU is installed on the right side of the rack. For redundancy, the PDUs in each pair should, if possible, be connected to two separate power sources.

If a hardware component has two power supplies. The left power supply connects to the left PDU. The right power supply connects to the right PDU.

To balance the HCP system electrical requirements across the PDU breakers and phases, the system hardware components connect to specific PDU outlets. These outlets are determined by the HCP system racking configuration and the PDU model.
