c) Set the keyed slots over the screws/pegs, and then slide the rail toward the front to lock it in place on the screw/pegs.
The rear key slot has a metal clip that locks over the screw/peg.
d) Using one M3x6mm screw, secure the inner rail to the side of the chassis to prevent sliding.
e) Install the second inner rail to the opposite side of the chassis and secure with the other M3x6mm screw.

securing plate that must be open before you can insert the mounting pegs into the rack-post holes.
On the outside of the assembly, push the green arrow button toward the rear to open the securing plate.
