4. Using the leveling bolts of rack 002, adjust rack 002 so that the joining holes of rack
002 align with the joining holes of rack 001. Refer to Figure 2-10.
5. Using the provided straps, screws, and washers; bolt the racks together in the four
designated locations shown in Figure 2-10.
6. If your system has additional racks, repeat Steps 4 and 5 until all of the racks are
bolted together.
7. Ensure that the circuit breakers on the power distribution units are in the OFF (0)
position. Then connect the power cords to grounded power outlets. Plugging in the
power cords ground the racks.
