Drobo 1200i not appearing in network

Ive got a second hand drobo that I’ve not been able to connect to my network. I did the password reset thing in the controller card and even did the pinhole resent there too. The network activity light lights up on the drobo and on the switch when connected but doesn’t appears on the dashboard nor I can see it on an ip scan. What am doing wrong? :frowning:

Any help would be really appreciated.
