Oh thanks for replying.
In that case is there any problem if I update the Firmware from 2.10 directly to the latest? Or I gotta update it gradually?
EDIT.: I just found out some info that I might have informed wrongly on the first post.
Different from Bay 2, Bay 3, 4 and 5 has the Power Mngt Controller at 3.3.
Updating the OA Firmware is still what gotta be done, right? I see its at 4.40.
