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.
