rear brackets should overlap. Use four mounting screws appropriate for your rack to attach the rear
bracket to the rack.
5. Connect left base bracket and rear brackets (see Figure 47 on page 138):
a. Insert six of the flat-head screws provided with the mounting brackets into the overlapping bracket
holes.

6. Position the right base bracket at the desired position in the right side of the rack opposite the installed
left base bracket, so that it is on the same rack level as the left base bracket. If the right and left base
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 base bracket's front screw holes with the holes in the rack. Use four mounting
screws appropriate for your rack to attach the right base bracket to front of the rack.
7. Position the other rear bracket at the right rear of the rack on the same level as the right base bracket,
so that the rear bracket overlaps with the right base bracket. The screw holes for connecting the base
and rear brackets should overlap. Use four mounting screws appropriate for your rack to attach the
rear bracket to the rack.
8. Connect the right base and rear brackets (see Figure 47 on page 138):
a. Insert six of the screws provided with the mounting brackets into the overlapping bracket holes.
