Problem solved, thank you everyone for suggestions. I couldn’t find anything that explains what the red on/off means, however I have determined it is related to the “backup” usb drive connected in the rear access connector. Once removed, the on/off turned blue and off to the races. I tried connecting the drive to front usb port only to hear continuous relay actuation with approx .5 Hz frequency, will investigate the external drive further, however NAS issue resolved. Cheers.
