4. Align the raised buttons on the sides with the matching slots in the DDM channel on the drawer.
Lower the DDM down onto the drawer, and rotate the DDM handle until the DDM snaps into place
under the DDM release lever.
Notes:
a. If the DDM does not seem not fully seated into the drive connector on the disk drawer, apply
downward pressure to the rear of the drive as you install it.
b. If the storage enclosure is turned on, you must wait at least 90 seconds after you install each
DDM in the drive drawer. Otherwise, the storage enclosure might not recognize the new DDM,
recognize the DDM as failed, or recognize the drive as incompatible. If this happens, unlatch the
DDM, wait 90 seconds, and latch the DDM again.
5. Install the other DDMs in rows from left to right until the drive drawer has a minimum of four
DDMs in the front row of the drive drawer.
6. Push the drive drawer into the storage enclosure until it clicks and close the levers on each side of
the drawer.
Attention: Make sure you push both levers back against the drive drawer completely so that the
drive drawer is closed. If the drive drawer is not completely closed, excess airflow through the unit
might cause damage to the DDMs. If the drive drawer is not completely closed, you will not be able
to open another drawer. If you try to force open another drawer, both drawers might be damaged.
7. Repeat steps 1 on page 38 through 6 for each drive drawer in the configuration.
8. Position the bezel in front of the storage enclosure as shown in the following illustration.
9. Align the tabs on the top and bottom of the bezel with the slots on the front of the storage enclosure,
and align the pins on the side of the bezel with the holes in the storage enclosure. Push the bezel
into the front of the unit until the latches on both sides of the bezel lock it in place.
