NOTE: If a storage system cabinet does not have components installed in the top four bays (bays

0–3, or the highest 16U of the cabinet), the two upper PDUs (PDU 0 and PDU 1) are not used to

power the system and need not be connected. Redundant power is still supplied to the lower bays

in the cabinet through PDU 2 and PDU 3.

Storage server 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, the four Power Distribution Units (PDUs) occupy the lowest chassis bay in the

cabinet.

Figure Figure 14 (page 29) illustrates the four PDUs at the bottom of a 3PAR cabinet.

Figure 14 Power Distribution Units

Each PDU has two power banks, each with a separate circuit breaker, to be used exclusively for

storage system components (Figure 15 (page 30)).
