1.3 Raised Floor Installations
A raised floor system provides a convenient way to duct cooling air and to route
power and communication cabling. Sun strongly suggests that the system be
installed on a raised floor to ensure that optimal cooling is available to the system.
The computer room floor must be able to support the weight of the system cabinets
(defined previously in
TABLE 1-1
). Each cabinet rests on four casters and four feet that
concentrate the weight of the cabinet on a small surface area.
Place perforated floor panels or floor grilles near or directly under the base of the
system.
FIGURE 1-6
illustrates the floor cutouts for cables. Suggested locations for
perforated floor panels or floor grilles are shown in
FIGURE 2-2
. Use the floor layout
diagram of the proposed location for the system shown in
FIGURE 1-6
to determine
the exact area required for your system. Ensure cabinets are positioned so all casters
and leveling feet are on solid raised-floor tiles.
Sun Microsystems™ suggests a minimum raised floor height of 24–36 in. (61.0–
91.5 cm).
1.4 Non-Raised Floor Installation
If you are not installing your system on a raised floor, ensure the cooling
requirements specified in
TABLE 2-2
can be met. Use cable covers to protect personnel
from injury and protect cables from damage.
Note – If the cooling to the system is inadequate, automatic system shutdown can
result.
