1. When two power supplies are operating, each power supply provides about half of the
required power for the storage system. When only one of the two power supplies is
operating, the power supply provides all required power for the storage system. Therefore,
use the power supplies that meet the rated input current for when one power supply is
operating.
The following table shows the supported input voltage and frequency for the controller
chassis, drive box, and node interconnect switch.

Use PDU with the standard plug.
■
If PDU is provided with connecting type B plug, use PDU with circuit breaker of 20
(16) A or less, or install circuit breaker of 20 (16) A in the power supply.
