■ a distance of 5cm minimum clearance to any obstruction to the front of 
the tray.
■ an open area of at least 50cm
2
 (8sq.in.) per tray of ventilation slots or 
louvres in front of the air intakes for the fans for each tray; for example 
ten 6×85mm (0.25×3.3in.) 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 50cm
2
 (8sq.in.) 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 base station is installed in a rack or cabinet with other equipment with 
different ventilation requirements, we recommend that the base station 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
/h (11cfm) 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 base station airflow 
requirements described above.
1.8 Installing the Base Station
1.8.1 Unpacking the Equipment
Unpacking the 
Base Station
The base station is packed in a strong corrugated cardboard carton with top 
and bottom foam cushions.
1. Cut the tape securing the flaps at the top of the carton and fold them 
flat against the sides.
2. Rotate the carton carefully onto its side and then onto its top, 
ensuring that none of the flaps is trapped underneath.
3. Slide the carton upwards over the foam cushions and lift it away. 
Remove the cushion from the bottom of the base station.
4. Lift the base station clear of the remaining cushion.
