Power supply LEDs

Power redundancy is achieved through two independent load-sharing power supplies. In the event of a

power supply failure, or the failure of the power source, the storage system can operate continuously on a

single power supply. Greater redundancy can be achieved by connecting the power supplies to separate

circuits. DC power supplies are equipped with a power switch. AC power supplies may or may not have a

power switch (model shown below has no power switch). Whether a power supply has a power switch is

significant to powering on/off.

NOTE: See Powering on/powering off on page 33 for information on power-cycling enclosures.
