3. Position the left base bracket at the desired position in the left side of the rack and line up its front
screw holes with the holes in the rack. Use four mounting screws appropriate for your rack to attach
the left base bracket to the rack.
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 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.
5. Connect left base bracket and rear brackets (see Figure 74 on page 206 ):
a. Insert six of the flat-head 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.

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.
