Install the disk array enclosure
There are two types of DAEs. One is a 3U 15 disk 3.5" drive DAE. The other is a 2U 25
disk 2.5" drive DAE. DAEs are optional. The installation procedures are slightly
different for each.

Installing snap-in rails in the cabinet
Note
The snap-in rails are dedicated left and right, and cannot be interchanged. The front
edge of each rail is stamped L or R for left or right side when the rail faces the cabinet
front.
The snap-in rails have two key tabs at the top and bottom edge on the rear of each
rail. The key tabs ensure that the rails are installed in the appropriate 2U space.
Procedure
1. From the rear of the cabinet, insert the two key tabs into the holes of the 2U-
space on the rear cabinet channel.

mounting holes until the spring clips snap into place on the outside of the rear
