SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
Figure 3–1. HSD-X Physical Placement Requirements
C. Environmental Requirements
The environmental requirements that must be considered during the physical placement
of the HSD and HSD-X transceivers are based on the RTCA/DO-160D Environmental
Specifications detailed in
"System Description" on page 1-1.
The standard mounting trays for the HSD and HSD-X offer a number of fan configuration
options depending on the physical placement of the LRU in the aircraft.
(1) Heating and Cooling
Refer to "System Description" on page 1-1 for a complete listing of the
RTCA/DO-160D Environmental Specifications for the HSD and HSD-X transceivers.
(a) HSD Transceivers
When selecting an installation location for the HSD transceiver, consider the
heating and cooling requirements listed below:
• Power Dissipation (DC models): 275 Watts nominal, 370 Watts maximum
• Power Dissipation (AC models): 275 Watts nominal, 385 Watts maximum
• Cooling Air: per ARINC 600
• Recommended Flow rate: 175 lbs/hr
• Pressure drop: 0.05”, ± 0.025” H
