Unlike the 2U, 25 and 3U, 15 DAEs, the 3U, 120 DAE is a drawer-type of DAE that slides in
and out of the 40U Dense rack. It is not fixed to the rack. The disk drives and fans for the
DAE are located inside the DAE.
To gain access to the DAE, you must first, open the console, then unlock and remove the
front bezel. Next, unlock the DAE from the rails by grasping the orange enclosure latch
handles (see location 1 in

Note: If the 3U, 120 (2.5-inch) DAE does not slide out of the rack (or cabinet) far enough
for you to access the internal components and lock on the rails in the service position,
verify that all the other DAEs are completely seated in the rack (or cabinet) by pushing
firmly on them.
Disk drives
The disk drives (hot-swappable) for the 3U, 120 (2.5-inch) DAE are encased in
cartridge-style enclosures. This enclosure is used so that varied types and sizes of disk
drives can be supported. Each cartridge has an easy-to-pull and push latch. The latch
allows you to quickly and efficiently snap-out a disk drive for removal and snap-in for
installation.
IMPORTANT
Removing a disk
Refer to the
DAE. Each disk contains LUN identifying information written when it was bound. Moving it
to another slot can make the information on the original LUN in accessible.
