Fully enclosed electrical cabinets are the preferred option for mounting your
ClearCube chassis. When using cabinets, make sure that both front and back 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 back of the chassis. 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
A 42U rack or cabinet with 14 fully loaded chassis units weighs approximately 1120
lbs. (507 kg), not including the weight of cabling or the rack itself. This results in a
loading of greater than 187 lbs. per square foot (913 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 14 chassis units. This allows 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 a chassis in a cabinet enclosure, never
use only one set of mounting brackets at the front. Select a cabinet
with an adjustable center rail or back rail in addition to the front rail.
ClearCube's adjustable mounting kit will then be required to attach
the chassis to both the front and center/back 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.
