Filler panel
Expansion units shipped without a full set of drives (14) contain filler panels
in the unused drive bays. Before installing new drives, you must remove the
filler panels and save them for later use. Each of the 14 bays must always
contain either a filler panel or a drive CRU.
Drive bays There are 14 drive bays that contain either a drive CRU or a filler panel.
Latch This multipurpose blue latch releases or locks the drive CRU in place.
Tray handle You can use this multipurpose handle to insert or remove a drive CRU.

drive activity.
