Attaching the Brackets
1.Measure the rack to determine if the two-post relay rack is 3 inches wide or
6 inches wide. The rearmost bracket on each side can be positioned for either 3- or 6-inch wide racks.
2.Align a bracket on the right side of the chassis, oriented so that the flange that fastens to the two-post rack is facing backward. The two top mounting holes must be aligned with the fourth and fifth holes on the side of the system chassis (see Figure 1-3).
3.Secure the front bracket to the system chassis using two 10-32 x 0.25-inch screws (see Figure 1-3).
Repeat this step to install the remaining front bracket to the other side of the system chassis.
