Drobo FS wont initialize

recently acquired from ebay - Have WB 1TB drives in each bay. After installing the dashboard and validing software is at the current version. Turned on drobo lights came on but after the self test the 1st bay indicator light came on solid red. Swapped out drives in bays same issue on all drives. I can send alert emails back and forth checkd firewalls and antivirus on laptop and on my asus router that it is attached to. checked my routers config and settings all looks good and current with the most recent firmware. I am now back to the drobo failure. I am looking for an understanding of steps to repair the unit.
