Abstract: A method of operation of a data storage system includes: providing a standby power source; detecting activity on a communication channel with an upstream re-driver powered with the standby power source; generating a signal-detect output from the upstream re-driver based on the activity; determining a link status with a power control unit based on the signal-detect output, the power control unit powered with the standby power source; and generating a power output from a power supply unit based on the link status, the power supply unit controlled by the power control unit.
