Drobo 5C boot issue

Hi, I hope anyone could help me with my issue.

My Drobo experienced several power cut from my UPS as my UPS was dying. After replaced by a new UPS, I turned on my Drobo, there are two situations:

  1. I hear vary loud fan, after one second the Drobo just shuts down it self.
  2. The Drobo didn’t shuts down itself, but the fan is still loud, after some time all the LED lights are on, but Drobo dashboard can’t find this device.

I tried take out all my drives but no help. It is out of warranty. I didn’t get Drobo Care. Not sure if I should purchase a Drobo Help ticket.
