Drobo powers on for a about 20 to 30 seconds and then powers off. The power light at the back of the unit is flashing the whole time. On the front of the unit all the lights come on, then the capacity lights go off, the drive lights are yellow whilst the unit is powering up, a few seconds later the whole unit powers off. The power light on the PSU is also on the whole time. I have removed all of the drives as well and get the same result. From reading similar posts here I suspect the PSU may be the issue.
Model: Drobo 5N
I have checked all connections and the unit hasn’t been moved or relocated recently.
