d. Simultaneously press inward and hold both drawer pull handles as you push the drawer closed until it
fully latches.

Populate the 5U enclosure
After successfully mounting the 5U chassis into the rack cabinet, populate the storage enclosure.
CAUTION If you partially populate the storage enclosure with drives in their carriers (DDICs), you must
comply with several additional requirements.
l
You must install a minimum of 14 DDICs. Populate in rows, 14 DDICs at a time, from front to back of the
drawer, and alternate between drawers.
a. Fill the front row in Drawer 1, then front row in Drawer 2.
b. Fill the middle row in Drawer 1, then the middle row in Drawer 2.
c. Fill the back row in Drawer 1, then the back row in Drawer 2.
The total number of populated drawer rows cannot differ by more than 1 row.
l
Populate rows with DDICs that have the same form factor and same rotational speed.
l
Do not mix drive types within the same drawer.
To populate the 5U enclosure:
1. Complete all actions to open the upper drawer. See "Access a drawer" on the previous page.
