8. Connect the cables that go between the racks.
9. If the racks are secured to a rack-mounting plate, torque the four bolts securing the rack to the rack
mounting plate to 54 - 67 newton-meters (40 - 50 foot-pounds), otherwise, go to step “11” on page
116.
10. After the racks are bolted down install the airflow plate to the front of the racks. To install the airflow
plate, complete the following tasks:
a. Position the airflow plate so that it rests on the rack-mounting plate.
b. Install two M6x10 flathead screws.
c. Use a torque screwdriver to tighten each screw to 2.5 Nm ± 0.2 Nm (22.1 inch lb ± 1.8 lbs).
11. If necessary, install a side panel on the end rack. For more information, see “Installing the side
cover” on page 128.
Attaching the stabilizer brackets
If the rack is not bolted to the floor, install the stabilizer bracket.
About this task
To attach the stabilizer bracket to the bottom of the rack, complete the following steps:
If you are connecting multiple racks for a 24-inch pitch, continue with “Connecting multiple racks with
rack-to-rack attachment kit for a 24-inch pitch” on page 112. If you are connecting multiple racks for a
600mm pitch, continue with “Connecting multiple racks with the rack-to-rack attachment kit for a 600
mm pitch” on page 114. If you are not connecting either, continue with the next step.
Procedure
1. Loosen the jam nut on each leveling foot (3) on each leveling foot, as shown in Figure 81 on page 117.
2. Rotate each leveling foot (3) downward until it contacts the surface on which the rack is placed, as
shown in Figure 81 on page 117.
3. Install the two mounting screws.
4. Adjust the leveling feet downward as needed until the rack is level. When the rack is level, tighten the
jam nuts against the base.
