9.
If your rack has unthreaded round or square holes, install 8 cage nuts in the appropriate
holes on the
right front and right rear rack posts, making sure that the 4 cage nuts on
each post are on the same rack level front and back.
Use Figure 37 on page 104 or Figure 38 on page 104 to help you with cage-nut installation.
10.
Position the right front adjustable mounting bracket at the desired position in the right
side of the rack opposite the installed left front bracket, so that it is on the same rack
level as the left bracket. If the right and left front brackets are not on the same level,
the chassis will rest at an angle in the rack instead of resting flat and level. Line up the
right bracket's front screw holes with the holes in the rack.
11.
Use 4 mounting screws appropriate for your rack—plus washers if you installed cage
nuts—to attach the right front bracket to the rack.
12.
Position the other rear bracket at the right rear of the rack on the same level as the
right front bracket, so that the rear bracket overlaps with the right front bracket. The
screw holes for connecting the front and rear brackets should overlap.
