If you are putting multiple chassis assemblies on a single power circuit, ensure that the
circuit can safely handle the combined maximum currents of all chassis.
When installing uninterruptible power supplies (UPS), consult your UPS
specifications for proper sizing. ClearCube provides kVA columns in the spreadsheets
for reference. See the ClearCube Power and Cooling Requirements Spreadsheets on
the ClearCube Support site at
http://www.clearcube.com/support/ for detailed power
and cooling requirements.
Additional Cooling and HVAC Considerations
As described above, obtain ClearCube Power and Cooling Requirements Spreadsheets
to determine cooling requirements for your ClearCube deployment.
Ensure that the air conditioning and ventilation system for the installation area can
accommodate the calculated thermal load. The rear of the chassis has air vents for four
fans. The fan openings must be at least four inches from any airflow-impeding barriers
such as walls, the back of the rack door or panel, large bundles of cables, and so on.
The availability of an air exit path from these fans is imperative to the efficient
operation of the unit. Failure to provide sufficient air venting will result in a thermal
overload of the blade. If the chassis is installed in a cabinet, use a fully-vented back
door or panel.
Cable Requirements
The chassis uses standard network cables with RJ45 connectors to connect to C/Ports
and to an Ethernet network. These can be CAT5, CAT5e, CAT6, or CAT6e cables.
C/Ports require straight-through cables with all four twisted pairs available. Network
connections follow standard Ethernet guidelines. In practice, identical copper media
can be used for C/Ports and for network connections, although ClearCube
recommends using different cable colors for C/Port and network connections to
simplify installation and maintenance. Throughout this guide, “C/Port cable” and
“network cable” refer interchangeably to copper-media cable such as CAT5, CAT5e,
CAT6, or CAT6e.
CAUTION: Make sure your power strips, power grid, and circuit
breakers can safely provide the required current. Ensure that any
extension cords used meet local safety regulations and local fire
codes.
CAUTION: Failure to provide sufficient space and room ventilation
will result in overheating that can cause eventual unit failure not
covered as part of the unit warranty.
