Equipment Ventilation
Always ensure there is adequate ventilation around the base station.
Notice Do not operate it in a sealed cabinet. You must keep the
ambient temperature within the specified range, and we strongly rec-
ommended that you ensure that the cooling airflow is not restricted.
Notice The cooling fans are mounted on the front panel and will only
operate when the panel is fitted correctly to the front of the subrack. To
ensure adequate airflow through the base station, do not operate it for
more than a few minutes with the front panel removed (e.g. for servicing
purposes).
Ambient Air Temperature Sensor
The ambient air temperature reading
for the base station is provided by the
ambient air temperature sensor board
b fitted to the PA control board.
The sensor board is inserted through
slots in the control board and heatsink
to be positioned between the heatsink
fins.
Notice If the sensor board is to provide accurate ambient temperature
readings, it must have forced airflow and must not come into contact
with the metal of the heatsink fins. Do not stack PAs with the fins
together. It is possible for the fins on one heatsink to slide between the
fins on the other heatsink. This can damage the sensor board, and possi-
bly result in the heatsink fins becoming locked together.
Cabinet and Rack Ventilation
The cooling airflow for the base station enters through the front panel and
exits at the rear of the subrack. For optimum thermal performance, the
heated air that has passed through a base station must not be allowed to re-
enter the air intakes on the front panel. Any space at the front of the cabinet
not occupied by equipment should be covered by a blanking panel. Refer
to Figure 3.1 on page 42.
