Floor tile cutouts
Raised flooring with tile cutouts to accommodate forced airflow and cable access (power
cables, braided ground strap, and fiber optic cables) requirements are preferred and
recommended.
For cooling requirements of the SAN256N director, raised floor tile positioning
requirements and measurements should be followed as indicated in the figure below for
each cabinet to be installed.
Floor tile cutout for cabling should be in accordance with the measurements shown in
the figure below; a 27.94 cm by 15.24 cm (11 inch by 6 inch) cutout in the front center of
one floor tile which is for the AC power and fiber optic cables. The second floor tile must
be a checkerboard perforated pattern, allowing a 60% open airflow area..
