Ventilation - Aastra AXD Installation And Maintenance Manual

3.8.7.1.2 INSTALLATION
The various specifications (connections, wiring, etc.) relating to the installation of the
external battery are described in the sections dealing with the power supply module
(see section 4.2). If a single battery pack is used for an entire A3XD, A3XL or A2XS iPBX,
see Figure 3.26 , Figure 3.27 and Figure 3.30 .
3.8.7.2

Ventilation

Aastra XD
Ventilation is provided by the 4 fans on the power supply units, which draw air from the
cabinet on the rear of the power supply module. Fresh air enters through the fresh air
inlets on the left side.
Nota : A single power supply unit is used in a simplex configuration. A ventilation unit
consisting of two fans is then added instead of the second power supply unit. No
matter the configuration, ventilation must be provided by four fans.
The fans are monitored by the two power modules, for a duplex configuration, and by the
power module and the ventilation module, for a simplex configuration (see Section 3.8.7).
Aastra XS/XL
Cooling is ensured by the 2 fans in the power supply unit (1 fan only for AXS, AXS12 and
AXS6) which extract air from the cabinet on the back plane of the power supply module
(left-hand side for AXS, AXS12 and AXS6). Fresh air enters through openings on the left-
hand side (right-hand side for AXS, AXS12 and AXS6).
The fan(s) is/are monitored by the power supply module (see section 3.8.7).
3.9 Different configuration options
The iPBX is preconfigured by default at the factory. Through programming, it is possible to
define other specific configurations: standard configuration, multi-company configuration,
multi-site configuration, hotel/motel and hospital functions.
It is necessary to determine which configuration is to be used before initialisation. Once
initialised, the programming tool proposes the menus specific to the configuration chosen
(see Section1.3, List of documents).
3.9.1 Configuration ex factory
The iPBX has a default configuration when it leaves the factory (default configuration also
obtained after a total reset). The system is fully functional and only requires a few
adjustments after initialisation to be completely operational.
