Drobo shut down. Loud Fan Noise. Toggle switch not working

I have a Drobo 5D. It’s 5 years old. It worked yesterday morning. In the afternoon there were no lights flashing, there was a loud noise sounded like a fan and the switch in the back did not work.
I shut down my computer then unplugged the Drobo. Does anyone know what the problem is and how to fix it. Thanks.

Have you checked the power transformer supply to the Drobo?

I’ve checked the power supply. I’ve plugged it directly into the wall outlet and still no power lights go on but when I plugged it into

The wall outlet I did hear hear the loud fan noise but toggle switch and lights still did not work.

Thanks for your quick response.

The fact that your fan did spin after you plugged it into the wall outlet still suggests to me that the power supply MAY be the culprit. It is certainly the cheaper item to replace, so I would recommend searching for a replacement power supply first.

Thanks for your help.
