SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
(c) HSD Fan Tray Requirements
WARNING: Failure to install and configure the fan tray assembly as instructed
may seriously compromise the HSD’s extreme temperature
operation.
Fan tray assemblies may be shipped with or without hole-plug-buttons installed.
For adequate airflow to the HSD subassemblies, the plugs must be installed or
removed in the fan/tray configuration as illustrated in
Figure 3–2. Installed plugs
are shown in black, and removed plugs are shown in white.
Figure 3–2. Fan Tray Plug Configuration
D. Chassis Grounding
The HSD and HSD-X tray-mounted assemblies must be electrically bonded to the
airframe. Ensure the mating surfaces are free from contaminants such as paints or other
non-conductive elements. Where surface preparations are insufficient to ensure a proper
bond, the use of a short, tin-coated, copper bonding strap of at least 1/4 inch wide is
recommended. The LRU and tray assemblies should provide a low impedance path of
<0.2 ohms.
