HP 3PAR cabinets contain four (PDUs) and each requires service from a dedicated single-phase
200-240 VAC (200-250 VAC International), 30-A (32-A International) grounded electrical circuit.
However, for optimal reliability and data accessibility, HP recommends a redundant AC
configuration that uses independent sources to provide a dedicated, grounded electrical circuit to
each PDU as shown in the following configuration:
NOTE: If a storage system cabinet does not have components installed in the top portion of the
cabinet, do not connect and use the two upper PDUs (PDU 2 and PDU 3) to power the system.
Redundant power is still supplied to the lower bays in the cabinet through PDU 0 and PDU 1.
Storage system PDUs are equipped with NEMA® L6–30 or IEC 60309 connectors, depending on
the region. International PDUs are equipped with IEC 60309, 2P+E (3 wire, 2 Pole + Earth Ground)
connectors. The appropriate receptacles or adapters are necessary at the operating site to
accommodate these connectors.
Power Distribution Units (PDUs)
For each cabinet, four Power Distribution Units (PDUs) are mounted vertically on the left side of the
rear of the cabinet. Numbers for PDUs are assigned beginning with 0, from bottom to top.
Figure 13 (page 32) illustrates the four PDUs in the HP P10000 3PAR Storage System cabinet.
