Installing the Hard Drives
Hard drives are connected to the backplane of the drawers using Disk Drive in Carrier (DDIC) hard drive
carriers.
The minimum number of drives in an SC180 expansion enclosure is 28 (one full, front row in the top
drawer and one full, front row in the bottom drawer).
1. Open the bottom drawer.
CAUTION: If the expansion enclosure operates for too long (depending on altitude) with a
drawer open, the expansion enclosure may overheat, causing a power failure and data loss.
Such use may invalidate the warranty.
a. Push and hold both drawer latches toward the center of the drawer.
b. Pull the drawer all the way out until it stops.
2. Insert each disk drive in carrier (DDIC) into the drawer, one at a time.
CAUTION: To maintain proper airflow, the drawers must be populated with drives in whole
rows (there are three rows of 14 drives per 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
drawer.
a. Hold the DDIC vertically and slide it most of the way into the slot.
b. Using both hands, apply downward pressure firmly and equally across the DDIC.
c. While maintaining downward pressure on the DDIC, slide the top plate toward the back of the
drawer until it clicks in place.
