For a while my 18 month old 5D3 has been shutting down during startup, requiring the power button to be pushed & held for several seconds until it starts booting correctly. About a week ago, I followed this process and the Drobo started up. After about 5 minutes it suddenly shut down and then the fan spun up to full speed & none of the lights lit up.
Since then, every time power is connected, the unit immediately goes to this state, even if the power switch is not pressed.
My suspicion is that something has failed and this is some sort of failsafe state. Has anyone else experienced this?
