DROBO S dont start up

Hi,
I have a Drobo S 1st Gen. MacBook Pro Retina 10.10.5.
Connect with an adapter to thunderbolt.
During the work the Drobo crashes/shuts down by it self, and began to restart and restart and restart again. And it won´t start again.
I try it at my old MacBookPro and it is the same sh**!

What happend? Is it possible that the power suppley crashed?

Please Help!!!

hi, you may be able to check if it is a drives problem or unit problem with the following test:

  • to power all down (including computer)

  • to remove all cables from drobo

  • to remove all your drives from drobo (remembering the order of your diskpack)

  • to power up the empty drobo
    (it should boot up and then go into standby mode)

  • to then power-up the computer

  • and once up, to connect the drobo to the computer (as you usuaully do, but also a separate test with direct usb if possible too)
    (does the drobo wake up shortly after, and then does dashboard recognise the drobo?)

Important:
all diskpack drives should only be removed when power is all OFF
all disk pack drives should only be put back in when power is all OFF
