SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL

F. CNX-250
The CNX-250 must be installed in a pressurized cabin.
Refer to CNX-250 Cabin Gateway Installation Manual, ATA No. 23-15
-18.
(1) Cooling Requirements
CNX Cabin Gateway products do not require external, forced-air cooling as
lon
g as clearance r
equirements 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.
(2) Clearance and Accessibility
Requirements
To support ma
intenance 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.
(3) Mounting Requirements
Attach the CNX-250 to a mounting surface using the mounting holes on the
baseplate.
(4) Installation Notes
Install the CNX-250 with cooling fins pointing up. To attach the CNX-250 on its
base (a
ny 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)).
G. CNX-900
The CNX-900 must be installed in the pressure and temperature controlled section
of th
e aircraft.
Refer to CNX-900 Next
Generation Cabin Gateway Installation Manual, ATA No.
23-15-88.
(1) Selecting a Location for the CNX-900 Router with Personality Module
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.
(2) Cooling Requirements
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.
