9.1. Installation of the rack with
ventilation facilities
To facilitate the renewal and circulation of the
air inside the rack, and the temperature of the
units and thus improve their characteristics, it
is advisable to place 2 ventilation units of 25W,
particularly when the rack with the DVBS2-
COFDM (CI) T0X is located in warm place, with a
temperature higher than 45°C.
These ventilators will be placed on a tray, that is
screwed onto the top part of the Rack, fig. 1 and
2. This way, the ventilators will force the fresh air
entering from the base of the cabinet, to circulate
between the modules and be expelled through a
gap on top of the cabinet (3-5 cm approx.). See fig.
