in the unused drive bays. Before installing new drives, you must remove
the filler panels and save them. Each of the 14 bays must always contain
either a filler panel or a drive FRU. Each filler panel contains a filler piece
for use with a slim drive.
Each drive CRU has a green Drive activity LED. When flashing, this green
LED indicates drive activity. When on continuously, this green LED
indicates that the drive is properly installed.
