Black Box 12U Installing Equipment in the Cabinet, Adjusting the Vertical Mounting Rails

Chapter 5: Installing Equipment in the Cabinet

5. Installing Equipment in the Cabinet

5.1 Leveling the Cabinet

Level the enclosure before installing equipment. The leveling feet at the corners provide a stable base if the floor is uneven, but they cannot compensate for a badly sloped surface.

1.Move the enclosure to a level location.

2.For each leveling foot, turn the leveling foot clockwise until it makes firm contact with the floor.

5.2 Adjusting the Vertical Mounting Rails

Vertical mounting rails are factory installed on the enclosure (see Figure 5-1) in the proper position to use with rackmountable equipment. The front mounting rails are adjustable towards the front or the rear of the enclosure to accommodate different rails or equipment with other depths. You can adjust the rails to be as close as 22.5" (57.2 cm) or as far as 30.25" (76.8 cm) apart.
