E3.S hard drives have Green LED and Blue/Amber LED.
The green LED is driven and controlled by the device. The two functions for this LED are defined as follows:
Power: This function indicates that the device has power and has no issues with its power regulation. Once the green LED is ON, it shall either remain ON or blink at the activity frequency unless the device determines power is no longer within its operating range.
Activity: This function indicates if the device is being used.
