34 • Network Planning and Site Preparation ClearCube Product Manual and Installation Guide
Fully enclosed electrical cabinets are the preferred option for mounting your
ClearCube Cages. When using cabinets, make sure that both front and rear panels
and doors are vented to provide sufficient airflow for intake and exhaust. If you plan to
use a cabinet enclosure, ensure that you have at least 34 inches (86cm) of interior
depth measured from the front of the unit, to accommodate the cabling that exits from
the rear of the Cage. Adequate space should be provided on the back of the rack or
cabinet to allow servicing the cables and equipment. Cabinets may be fitted with
casters for easier mobility or service access.
Space and Floor Support Requirements
An 84-inch (2.1 m) tall rack or cabinet with fourteen fully loaded Cage units weighs
approximately 1190 lbs. (540 kg), not including the weight of cabling or the rack itself.
This results in a loading of greater than 198 lbs. per square foot (970 kg per square
meter) for each of the roughly 6 square feet (0.56 square meters) of floor space
required per rack.
Verify that both the rack and floor will support this weight, even if initial installation
does not include fourteen Cage units. This will allow for future expansion at the
selected location. If other equipment is to be installed in the rack or cabinet, take this
additional weight into consideration.
CAUTION: Equipment racks and cabinets can become highly unstable if
not adequately secured. Please read and follow the manufacturer's
specifications and recommendations for mounting instructions.
Additional ClearCube guidelines are provided throughout this section
that – with the manufacturer's requirements – will ensure a safe
installation.
WARNING – When installing Cages in a cabinet enclosure never
use only one set of mounting brackets at the front. Select a cabinet
that has an adjustable center rail or rear rail in addition to the front
rail. ClearCube's adjustable mounting kit will then be required to
attach the Cage to both the front and center/rear rails.
WARNING – Improper structural support could cause the rack or
cabinet to lean and the floor to buckle, possibly to the point of
structural damage.
