Step 2 Attach the inner rails to the sides of the chassis:
a) Remove the inner rails from the slide rail assemblies.
b) Align an inner rail with 1 side of the chassis so that the 3 keyed slots in the rail align with the 3 pegs on the side of
the chassis.
c) Set the keyed slots over the pegs, and then slide the rail toward the front to lock it in place on the pegs. The rear key
slot has a metal clip that locks over the peg.
d) Secure the inner rail to the side of the chassis using 1 M3X6mm screw.
e) Install the second inner rail to the opposite side of the chassis and secure with the other M3X6mm screw.
