1: Installation and Operation
Attaching the Slide Rail to the Rack
To attach the slide rail to the rack, follow these steps:
Tip: The slide rails must be level in the rack. To ensure that you install the slide rails
correctly, carefully count the mounting holes on all of the rack rails (two front rails and
two rear rails).
1. Locate eight 10-32 x 1/2-in. Phillips screws, eight shoulder washers, and four
barnuts.
2. Place one of the barnuts inside the rack and align it with the second and third holes
of the selected 2U of space (see Figure 1-16).
Note:
The holes in the barnuts are not centered. The barnuts need to be placed in
such a way that the holes are closest to the inside edge of the rack rails. See
Figure 1-16.
3. Insert two screws with shoulder washers through the rack rail to hold the barnut in
place. The screws should not be tightened at this point.
4. Repeat steps 2 and 3 to install the remaining three barnuts on the other three rack
rails (front and rear of rack).
