Figure 17. Removing a DDIC
1. Drive fault LED 2. Release button
3. DDIC
NOTE: Leave the drive in the carrier. The replacement drive will come in a carrier and
attempting to remove the carrier can cause the carrier to break.
7. Lower the replacement DDIC into the slot then push and hold the DDIC down while sliding it toward
the back of the enclosure until the DDIC latches to the backplane.
CAUTION: If the DDIC fails to latch, do not use it and request a replacement. If a faulty DDIC
unlatches within a closed drawer, it can make the drawer unable to be opened.
CAUTION: To maintain proper airflow, the drawers must be populated with drives in whole
rows at a time (there are three rows of 14 drives per drawer). The minimum number of drives
in an enclosure is 28 (one full, front row in the top drawer and one full, front row in the
bottom drawer), the number of populated rows between drawers must not differ by more
than one. Populate the rows from the front to the rear of the enclosure.
