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.
