36. If you have multiple racks that are connected in a suite (bolted to each other), go to “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 600 mm pitch, continue with “Connecting multiple racks with the
rack-to-rack attachment kit for a 600 mm pitch” on page 114. Otherwise, torque the four bolts to 54
- 67 newton-meters (40 - 50 foot-pounds).
37. After the rack is bolted down, install the airflow plate to the front of the rack. To install the airflow
plate, complete the following tasks:
a. Position the airflow plate (1) so that it rests on the rack-mounting plate.
b. Install two M6 x 10 flathead screws (2).
c. Use a torque screwdriver to tighten each screw to 2.5 Nm ± 0.2 Nm (22.1 inch lb ± 1.8 lbs).
