Figure 88. Attaching the rack to a raised floor
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).
