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. 1 1 2 2 AC model DC model LED Description Definition 1 Input Source Power good Green - Power is on and input voltage is normal.
