TB7100 Installation Guide
© Tait Electronics Limited May 2005
To allow enough cooling airflow through a cabinet mounted base station we
recommend the following:
■
a distance of 5cm minimum clearance to any obstruction to the front of
the tray.
■
an open area of at least 50 cm
2
(8 in
2
) per tray of ventilation slots or
louvres in front of the air intakes for the fans for each tray; for example
ten 6x85mm (0.25x3.3in) slots will allow the recommended airflow.
■
a distance of 10cm minimum clearance to any obstruction to the rear of
the tray.
■
an open area of at least 50 cm2 (8 in
2
) per tray of ventilation slots or
louvres in the top of the cabinet, or to the rear of each tray.
■
a 2U gap at the top of the cabinet
Note
The ventilation opening must be unrestricted. If the slots or holes
are covered with a filter, mesh or grille, the open area must be
increased to allow the same airflow as an unrestricted opening.
The maximum ambient temperature entering the cabinet must not exceed
the maximum temperature specified for the base station.
If the TB7100 base station is installed in a rack or cabinet with other
equipment with different ventilation requirements, we recommend that the
TB7100 be positioned below this equipment.
Auxiliary Extractor
Fans
If multiple base stations are fitted in a cabinet, auxiliary extractor fans may
be required to ensure adequate cooling. If fitted they should be capable of
extracting 18m
3
/hr. (11 cfm) per base station in the cabinet.
If you have any other configuration, the performance of your system will
depend on how closely you comply with the TB7100 base station airflow
requirements described above.
