Drobo 5D - Stuck in "Initial Setup"

Hi all,

I’ve just bought a Drobo 5N, put 5 x brand new 8TB HDDs in it and switched it on! It’s showing up in Drobo Dashboard for a couple of minutes and is then dropping out again, and then showing up again, and the cycle continues.

When it is showing it all looks healthy other than it says at the bottom of the Dashboard going through “initial setup” and that it will take about 30 minutes, It’s already take a few hours.

Any idea what’s happening here?

What hard drives (Make & model)?
It could just be underestimating the time.
Is it just dropping off dashboard? Or is it boot looping?
