the system’s cooling. The six fans are disposed on two rows and are DC supplied
through the relevant connectors placed on the Board Backplane.
In order to make more uniform the system’s ventilation , the fans have been placed
about 3 cm far from the boards so that ventilation from all sides is adequate. As a
consequence, DO NOT COVER THE BOTTOM AND TOP GRIDS under any
circumstances.
CAUTION
THE BOTTOM AND TOP GRIDS OF THE FAN TRAY UNIT
MUST NOT BE COVERED UNDER ANY CIRCUMSTANCES!
CAUTION
THE EXTRACTION OF THE FAN TRAY UNIT BOX CAN BE PERFORMED BY
QUALIFIED PERSONNEL ONLY!
The position of the fan tray inside the mainframe (looking from the rear panel) and the
direction of the air flow are shown in Fig. 3.2.
The fans start to work as soon as the system is powered ON, either remotely via the
relevant input signal or locally by turning on the power-ON key (refer to Section 3.4.2,
p.23).
Please note that the maximum allowed temperature for the operation of the fan tray unit
is 40°C.
