Note: If the hole locations selected at the rear of the rack are not accessible, riggers will be required
to install the mounting hardware in the non-accessible hole locations. You must lift the rack to install
the hardware.
22. If you are installing a 7014-T42 rack with the X brace feature, go to step “27” on page 18.
Otherwise, continue with step “23” on page 18.
23. For each rack-mounting plate, select at least two suitable hole locations (A). Select the hole locations
as close to the threaded hole areas as possible. Drill pass-through holes at the selected locations into
the raised floor panels. The pass-through holes allow the mounting hardware to be inserted into the
rack-mounting plate and pass through the raised floor panel to the concrete floor.

26. Go to step “30” on page 19.

locations as close to the threaded hole areas as possible. Drill pass-through holes at the selected
locations into the raised floor panels. The pass-through holes allow the mounting hardware to be
inserted into the rack-mounting plate and pass through the raised floor panel to the concrete floor.
