Red light. rapidly flickering

I have G Raid Thunder bolt with two disc drives (6GB). it shows a rapidly flickering red light with accompanying soft noise.
I open the chassis door. Both drives showing red. If I remove both drives and power the unit on the red light comes on and the same noise persists. in other words, the noise isn’t coming from the drives. Are both drives fried? or is this a chassis problem??
