1 At the front of the rack cabinet, position one of the mounting rails so that its mounting-bracket flange
fits between the marks you placed (or numbered locations) on the vertical rails in "Marking the Rack"
on page 9 (see Figure 1-6).
The three holes on the front of the mounting-bracket flange should align with the holes between the
marks you made on the front vertical rail.

bracket flange to secure the mounting rail to the front vertical rail.
3 At the back of the cabinet, pull back on the mounting-bracket flange until the mounting holes align
with their respective holes on the back vertical rail.
4 Install two 10-32 x 0.5-inch flange-head Phillips screws in the upper and lower holes in the mounting-
bracket flange to secure the mounting rail to the back vertical rail.
5 Repeat step 1 through step 4 for the mounting rail on the other side of the rack.
NOTE:
Ensure that the mounting rails are mounted at the same position on the vertical rails on each side
of the rack.
