Drobo Wont Power On

My drobo for some reason stopped powering on. The power brick light is solid green when only plugged into the wall, but pulses green when plugged into the drobo. I’m looking at my options to retrieve the data from the drives with a new drobo, but am concerned about the firmwares not matching. I am not sure what firmware the dead drobo is on and am wondering if there’s anyway to find that out.
