Hello, 

 From this info it appears you did not shutdown the array first, but just removed the power. Is that correct? 

  Both the GUI and the CLI have a shutdown option.  Which should always be done before power off the array. 

  Do you know the version of the firmware it was running at the time? 

  Only the serial port is going to be available at this time as I suspect the power up sequence has not completed. 

  I suspect you do no have a support contract on this array. Depending on where you are you can purchase a one time support call and with the serial port connected they will attempt to triage the issue. 

 Otherwise you would likely need to reset and reconfigure the array from scratch 

 Regards, 

Don
