2.8.3 Remote Mounted Stand-Alone Rack Considerations
Figure 2-3 and Figure B-4 show the GIA 63(W) remote mounted stand-alone rack. The remote rack can be
installed in a variety of locations, such as the electronics bay, under a seat, or on an avionics shelf behind
the rear baggage area. Refer to Figure 2-5 for suggested mounting locations. Leave sufficient clearance
between the GIA 63(W) and any obstruction. The rack should be mounted to a surface known to have
sufficient structural integrity to withstand additional inertia forces imposed by a 7.5-pound (3.4 kg) unit.
Figure B-3 gives the GIA 63(W) stand-alone rack dimensions. The rack can be mounted vertically using
four #8-32 pan head screws (MS35206, AN526, or other approved fastener). It can also be mounted
horizontally using four #6-32 100° counter-sunk flathead screws (MS24693, AN507R, or other approved
fastener). Ensure that the GIA 63(W) chassis has a ground path to the airframe by having at least one
mounting screw in contact with the airframe.
Figure 2-4 and Figure B-6 show the stand-alone rack used for the GIA 63H installation. Figure B-5 gives
the stand-alone rack dimensions for the GIA 63H. The rack can be mounted in any orientation using
screws as defined in Section 2.1.3. Ensure that the GIA 63H chassis has a ground path to the airframe by
having at least one mounting screw in contact with the airframe.
After the cable assemblies are made and wiring installed to the rack back plate, route wiring bundle as
appropriate. Use cable ties to secure the cable assemblies and coax to provide strain relief for the cable
assemblies.
