I just purchased a 4TB nas, connected lan cable and power-supply, but the device shows the power-on led and the 4 disks led blinking of green colour.
I tried to reset it but the situation doesn’t change: when i turn on the device, after a few of seconds the four leds start blinking permanentley, and it is not possible to connect to the nas.
Do you have a DHCP server running in your network?
How did you try to access the NAS after powering it on? E.g. did you try to access the web interface?
If - for any reason - your NAS is trying to create an initial setup, you should be able to watch the progress on the web interface. This initial setup could take up to 2 days (with my box it took 16 hours). During that time, you can’t access the box except for watching the setup in the web interface.
