2.7.1 Remote Mounted Stand-Alone Rack Considerations
Figure 2-2 and the drawing in Appendix B show the GTX 3000 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 2-3 for suggested location. Leave sufficient
clearance between the GTX 3000 and any obstruction. Install the rack in accordance with AC 43.13-2A
Chapter 2 “Radio Installations”. The rack should be mounted to a surface known to have sufficient
structural integrity to withstand additional inertia forces imposed by a 4.3-pound (1.95 kg) unit. If it is
necessary to build a shelf or bracket to mount the GTX 3000 stand-alone rack or it is not certain that the
chosen location is of sufficient structural integrity, refer to Appendix A for validation of rack mounting
structures and determining static load capability.

Figure B-1 gives the GTX 3000 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 GTX 3000 chassis has a ground path to the airframe by having at least one
mounting screw in contact with the airframe. If more water-resistance is desired, the rack should be
installed in the upright vertical orientation only, otherwise, the rack may be mounted in either vertical or
horizontal orientation.

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.
