2) Repeat the last step to place two marks on the corresponding mounting holes on thefront-right side of the rack.3) Go to the back of the rack. On the left side, find the EIA unit that corresponds to the lowestEIA unit marked on the front of the rack.4) Mark the top mounting hole (C) of this EIA unit. Count up two holes and place another markbeside that mounting hole (D).5) Repeat the last step to place two marks on the corresponding mounting holes on therear-right side of the rack.3. Install the rail assembly into the rack as follows:Important: To complete this procedure, use two people to attach the rail assembly to the rack.Position one person in front of the rack and one person at the back of the rack.CAUTION:Installing the rails in the rack is a complex procedure. To install the rails correctly, you mustperform each task in the following order. Failure to do so might cause rail failure and potentialdanger to yourself and the system unit.a. Loosen the two rail-adjustment screws on one rail just enough to enable the rails to slide.b. Locate the marks previously made on the Electronic Industries Alliance (EIA) strips at the frontand back of the rack cabinet. Use the L or R imprinted on the front bracket of your first rail toalign it with these marks within the matching side of the rack cabinet. The bottom of the railsupport ledge should be slightly above the U mark on the rack flange.The rail comes with two spacers in the front bracket and two spacers in the rear bracket. If therack has round holes, the spacers on the rail brackets fit into the round holes in the rack flanges.If the rack has square holes, replace the set of small spacers on the front and rear of the rail withthe larger spacers that are included with the rail kit.Figure 2.
