D. CCU-200
You can install the CCU in a pressurized or non-pressurized environment.
Figure 3-9 on page 3-17 illustrates the physical and mechanical specifications of
the CCU-200.
(1) Physical Placement
Bolt the CCU to a flat surface within the aircraft cabin in any orientation. Install
the mounting flange of the CNX CCU using four 10-32 bolts.
The CCU must have two inches of clearance on all sides.
For installations that require DO-160E Category W waterproofness, you must
install the CCU on a horizontal surface with the mounting flange on the bottom.
(2) Environmental Requirements
The CCU meets DO-160E requirements, and does not require additional
cooling.
E. CNX-200
28B
CNX Cabin Gateway products must be installed in the pressurized cabin.
Section “CNX-200Series 2 Network Accelerator on page A-10 provides information
about the environmental characteristics of the CNX Cabin Gateway.
(1) Cooling Requirements
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-200 products with cooling fins pointing up.

Clearance and Accessibility Requirements
To support maintenance and troubleshooting of the unit, install the unit in a
location that provides access to the connector panel.
CNX-200 products must be installed in a location that provides clearances of
at least three inches (3") of air space above the unit and one inch (1") of
clearance in front of the connector panel.

Mounting Requirements
Mount the unit using four 10-24 bracket fasteners. Install two fasteners on each
side panel or on the front and back panel of the unit, depending on the
requirements of the installation location. Refer to the outline and installation
drawing provided in Figure 3-9 on page 3-17
XX
and Figure 3-10 on page 3-19.
Use sixteen (16) screws (MS81957-28B) and washers (NAS620C6LP) to
attach the fasteners to the unit and installation mounting holes.
