DDIC in a ME484 JBOD Storage Enclosure
Each disk drive is installed in a DDIC that enables secure insertion of the disk drive into the drawer with the appropriate SAS carrier
transition card.
The DDIC features a slide latch button with directional arrow. The slide latch enables you to install and secure the DDIC into the disk slot
within the drawer. The slide latch also enables you to disengage the DDIC from its slot, and remove it from the drawer. The DDIC has a
single Drive Fault LED, which illuminates amber when the disk drive has a fault.

Populating drawers with DDICs
The ME484 JBOD storage enclosure does not ship with DDICs installed. Before populating drawers with DDICs, ensure that you adhere to
the following guidelines:
• The minimum number of disks that are supported by the enclosure is 28, 14 in each drawer.
• DDICs must be added to disk slots in complete rows (14 disks at a time).
• Beginning at the front of each drawer, install DDICs consecutively by number, and alternately between the top drawer and the bottom
drawer. For example, install first at slots 0–13 in the top drawer, and then 42–55 in the bottom drawer. After that, install slots 14–27,
and so on.
• The number of populated rows must not differ by more than one row between the top and bottom drawers.
• Hard disk drives (HDD) and solid-state drives (SDD) can be mixed in the same drawer.
• HDDs installed in the same row should have the same rotational speed.
The following figure shows a drawer that is fully populated with DDICs:
