4. Position one of the rear brackets at the left rear of the rack on the same level as the left base bracket, so that the rear
bracket overlaps with the left 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.
5. Connect left base bracket and rear brackets (see Figure 6):
a. Insert six of the flat-head screws provided with the mounting brackets into the overlapping bracket holes.
b. Tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips screwdriver.

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 6):
a. Insert six of the screws provided with the mounting brackets into the overlapping bracket holes.
b. Hand-tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips screwdriver.
