Chassis And Blade Power Requirements; Power Input Considerations - ClearCube A1010 User Manual

• The rear of the chassis has air vents for the blade fans. The fan openings must be at least
four inches from any airflow impeding barriers such as walls, the rear 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 rear door or panel.
• Each chassis produces varying amounts of heat, depending on processor activity. See
"Power and Thermal Specifications for A–Series
information about the power requirements, maximum power wattage, and thermal
specifications for various chassis and blade configurations.

Chassis and Blade Power Requirements

Your ClearCube system centralizes computing components in a single location, which
centralizes power requirements to one area. Although the ClearCube solution reduces the
overall power required when compared to traditional PCs, the power demands in the IT center
are increased. Use the power and current specifications in this section to ensure that your
facilities can provide the required power safely without tripping circuit breakers.

Power Input Considerations

The following sections detail items to consider when addressing power input for the A3100
and A3000 chassis.
Chassis have two separate power inputs. Each input provides power to half of the chassis.
• You must connect both powers cords to the chassis.
• The maximum steady-state current draw of a single fully loaded chassis ranges between 7
and 12 amperes at 120 VAC per input, based on the level of user activity.
• Peak initial current draw is 12 amperes per input.
See the tables in
for more information.
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.
