CNX Cabin Gateway products do not require external, forced-air cooling as
long as clearance requirements are maintained and ventilation is provided as
required to ensure that the maximum operating temperature does not exceed
131°F (55°C). Honeywell recommends providing ventilation for all CNX-200
products installed in enclosed spaces.
Install CNX-250 products with cooling fins pointing up.
To support maintenance and troubleshooting of the unit, install the unit in a
location that provides access to the connector panel.
CNX-250 products must be installed in a location that provides clearances of
at least two inches (2") on all sides.
At
tach the CNX-250 to a mounting surface using the mounting holes on the
baseplate.
Install the CNX-250 with cooling fins pointing up. To attach the CNX-250 on its
base (any configuration), use the four mounting holes in the baseplate flanges.
These mounting holes are designed for use with #10 hardware (3/16 or 0.190
inch (4.76 mm)).
The WLAN antenna should be located in an area of the aircraft cabin to provide
satisfactory coverage of the entire aircraft. In general, a mid-cabin location is
ideal. For antenna separation use at least 20 cm (7.8 inches). The WLAN
antenna may be located behind the cabin interior, but must not be located
behind metallic panels or surfaces.
CNX-900 does not require external, forced-air cooling when installed in the
pressurized cabin. However, it is very important that enough clearance exist
so that convective air can flow around the CNX-900 unit. Forced air-cooling is
required for operation outside of the pressure and temperature controlled
areas.
