7.1. Installing Rack with Ventilation

To encourage air renewal and circulation inside
the rack, thereby reducing the temperature of the
units and improving their features, installing 2 25W
ventilation units is recommended, especially when
the rack with the units is in a warm environment
above 45°C.

This cycle must flow correctly and the following
should be avoided:
- Opening the side doors, as this will cause the
ventilators to take in exterior air instead of inte-
rior air.
- Placing objects next to the rack that cover the air
intake or output.
- In cases where the rack is not complete, subracks
should be placed from top to bottom without
leaving any space in between, fig 4.
These ventilators will be placed on a plate bolted
to the top of the rack, fig. 1 and 2. Thus, the ventila-
tors will circulate fresh air entering the back of the
cabinet (fig. 3), and expel it through the aperture (3
to 5 cm) at the top.

7.2. Installing Rack without Venti-
To install rack mount units without ventilation,
when the rack is in locations with an ambient
temperature around 45°C, the rack should be
installed fully open, e.g., doing without the side
doors to facilitate unit ventilation, fig. 5.
