5N issues

My 5N all of a sudden does not have an icon on my screen (MAC). It is seen on dashboard but it has a lock next to it which I don’t recall seeing in the past. I do not have the password for it so that is done. But the unit fires up showing all the lights and then settles down to only a dimly it power light. No side lights, nothing.

hi schlossed, can i check if this is the same drobo which you mentioned here:
(and is it the drobo that you mentioned there as only having a power light, or the other one?)
