Step 5. Attach the rack to a concrete floor beneath a raised floor
Perform the following steps to attach the rack-mounting plates to the concrete floor beneath a raised
floor.
Refer to Figure 88 while you perform the steps.
1. Ensure that the rack is in the correct location.
2. In this rack, temporarily install the bushings to help position the rack-mounting plates.
3. Ensure that the bushing is in the leveling foot. Position the two rack-mounting plates in the
approximate mounting locations under the rack. If necessary, raise the leveling feet for clearance.
4. Place a bushing on a rack-mounting bolt. Insert the bolt and bushing through the leveling foot and
bushing, and out of the bottom bushing.
5. Insert the four rack-mounting bolts through the leveling feet and bushings, and out the bottom of
the rack.
6. Position the rack-mounting plates under the four rack-mounting bolts. Center the rack-mounting
bolts directly over the tapped holes.
7. Turn the rack-mounting bolts 3–4 rotations into the tapped holes.
8. Mark the raised-floor panel around the edges of both rack-mounting plates.
9. Mark the rack-mounting plate bolt-down holes that are accessible through the opening in the rear of
the rack.
10. Remove the rack-mounting bolts and bushings.
11. Remove the rack-mounting plates.
12. Loosen the locking screws on the casters. Move the rack so that it is clear of the locator marks for
the rack-mounting plates.
13. Position the rack-mounting plates within the marked areas.
14. Mark the raised-floor panel at the center of each hole in the rack-mounting plates (including the
tapped holes).
