Drobo Gen 1 Problem

I need to use again my old DR004D-U + DR00D-E but DroboDashboard can’t find my Drobo.

I tried DR004D-U connected via USB directly to my computer and works OK.

It’s possible to find DR004DU manual?? I’am trying to dowload it from Drobo web but I can’t find it.

Anyone can explain me how to reset to factory defaults the DR00D-E Droboshare? What is the default IP address?

Thanks in advance.
