First startup, on/off led blinking yellow, drive leds blue

When I for first time power on the WD My Cloud Mirro 8Tb after abt. 1-2 minutes the disk leds are steady blue but the onn/off led is blincking yellow. This must also be blue. there is no connection at all. 

Is this correct or is there something wrong?

You’ve plugged it into your network?

Thx, it’s ok now
