Can anybody point me to the Drobo4D-D manual?

Can anybody point me to the Drobo4D-D with NAS manual? The drobo documentation website doesn’t seem to have this manual (http://www.drobo.com/documentation/). A quick Google search of some other forums shows that others have been looking for this manual with no success.

Thanks!

Do you have a 4-bay Drobo or a NAS Drobo? They don’t make a 4-bay NAS model.
