Use the four remaining #12-24 self-tapping screws to fasten the 
chassis to the rack/cabinet supports (two screws on each side).
 
Make sure that the back of the chassis is on the chassis guide 
brackets. See Figure 35

If you want to add a Chassis Expander, follow the above steps.
You only need to leave a small space between the Main Chassis and 
the Chassis Expander. The air circulates from the side of the chassis. 
To install the Chassis Expander, start in the next 5u pattern of 
mounting holes. This results in the Chassis Expander being 
approximately 1/4 inch from the first chassis.
Note: In the 5u pattern, a “u” is equal to 1.75 in. and includes three 
holes spaced at 5/8 in. + 5/8 in. + 1/2 in.

screws on 
each side to
