Mark the references and the layout lines.
To avoid cumulative errors when laying out short dimensions in a straight line, first mark the
total length, then divide it into shorter lengths leaving the measuring tape in place.
Where the layout lines intersect, extend the lines at least 6 in. (15.24 cm) beyond the point
of intersection to check the equipment alignment.
Mark the rack position on the floor with a chalk line, referring to the job floor plan. This position
should provide an optimal space for cable routing.
Note 1 — The maximum allowable horizontal alignment deviation of the
joined ends of racks cannot be more than 1/16 in. (1.6 mm).
Note 2 — In earthquake zones, place anchors as close to the four
corners of the rack as possible.
STOP. This procedure is complete.
To drill floor for anchoring 23 in. rack
Review the anchor points for each rack, using the rack base as a template.
Note 1 — Precision spacing between racks is critical, because rack
ends are not adjustable. Install the floor anchors for each rack only after
the previous rack is mounted and attached.
Note 2 — For non-seismic qualified installations, typically four anchors
are used for concrete flooring, however sometimes two anchors may be
used if the rack is also supported from overhead.
Note 3 — For seismic qualified installations, always use four anchors
placed as close to the four corners of the rack as possible.
Cover the surrounding floor area with protective covering as required by local practice.
Put on the safety glasses.
Danger — If drilling asbestos flooring, use only the approved tools and
packing materials for debris removal.
