11. Mark the floor around the edges of both stabilizer brackets.
12.
Mark the plate bolt-down holes that are accessible through the opening in the rear of the rack.
13. Remove the rack-mounting bolt assemblies.
14. If you are installing an ac-powered rack, remove the bottom isolator bushing from each of the
leveling feet.
15. Remove the stabilizer brackets from the marked locations.
16. Loosen each of the locking screws on the casters.
17. Move the rack so that it is clear of both areas that were marked on the floor for the stabilizer bracket
locations.
18. Reposition the stabilizer brackets within the marked areas.
19.
Mark the floor at the center of all holes in both stabilizer brackets.
20. Remove the two rack-mounting plates from the marked areas.
21.
At the marked location of the threaded rack-mounting bolt holes, drill four clearance holes into the
concrete floor. Each clearance hole should be approximately 1-inch deep. This depth allows the
rack-mounting bolts enough room to protrude past the thickness of the stabilizer brackets.
