DROBO GEN 2 Keep rebooting?

Does anyone know why my Drobo is rebooting? It gets to 2 blue lights and showing all green on the right hand side then goes through the motions again? ANy help?much appreciated.

Taking a guess, I’d suggest try with a different power supply. Failing power supplies aren’t that uncommon, internal capacitors degrade with age & the unit stops being able to deliver the full demand.
