One Red Light

I have a red light on one of my un-used bays. Is that normal?
Thanks

Most likely the Drobo is asking you to insert a drive for increased capacity. What Drobo model are you using?

Gen 1 I think as I’ve had it for a long time.

The Gen 1 machines are USB only. If it also has firewire it is a Gen 2 Drobo.
