Attaching the stabilizer brackets
You might need to attach the stabilizer brackets to the rack. This section helps you determine whether
stabilizer brackets are necessary and describes how to attach them if needed.
If the front or back ac electrical outlets are going to be installed in the rack, you cannot attach the
stabilizer brackets. The rack must be bolted to the floor. Stabilizer brackets are used only if you will not
be bolting the rack to the floor. If you are going to bolt the rack to the floor, go to “Attaching the rack to
a concrete floor” on page 6.
To attach the stabilizer brackets to the bottom of the rack, do the following:
Note: Before installing the stabilizer brackets, see “Attaching the front or back ac electrical outlet” on
page 16 for instruction on installing the ac outlet-mounting plates.
1. Align the slots of one of the stabilizer brackets with the mounting holes at the bottom front of the
rack.
2. Install the two mounting screws.
3. Ensure that the base of the stabilizer bracket rests firmly on the floor. Use the Allen wrench that was
supplied with the rack to tighten the mounting screws alternately until they are tight.
