8. Adjust the outer slide-rail brackets to fit the depth of the rack cabinet, and then
attach the front of the slide-rail brackets to the rack cabinet, using four screws.
Make sure that the slide-rail brackets extend outside of the rack-cabinet
mounting flanges.
Note: Do not install screws in the middle holes in the slide-rail bracket. These
holes are for the thumbscrews on the front of the console unit.
