the sides of the rack. The brackets combine with a vertical 6x16 metric hex flange bolt to make
the D-Rack Stiffener assembly.
Note: Installation and use of the D-Rack Stiffener assembly is important because of the extremely
heavy system weights that can occur with SGI NAS JBOD configurations.

Due to their construction, it is easiest to attach the outer bracket to the rack first, before joining
with the inner bracket to make the D-Rack Stiffener.
1. Attach the outer bracket of the D-Rack Stiffener to the D-Rack using the four support
screws. There are six holes available for the screws, but two will be blocked. Use the
remaining four holes.
Note: The screws that attach the D-Rack Stiffener to the rack can be tightened all the way.
2. Attach the inner bracket to the outer bracket using the vertical bolt and socket wrench
(Figure 2-7). Do not tighten these bolts all the way. They will be used later for altering rail
aligning using the alignment tool.
