3.2.3 Shelter configuration. The shelter shall meet the configuration

constraints specified on interface drawing 17-2-0035 for the shelter type

specified.

3.2.3.1 Shelter flatness and squareness. Shelter surfaces shall be flat and

square. Each surface of the shelter shall be flat within 1/8 inch per each 48

inch length. Adjacent surfaces shall be perpendicular within 0.10 degrees.

3.2.3.2 Shelter dimensions. The shelter shall meet the dimensional constraints

within the specified tolerances required by interface drawing 17-2-0035 for those

dimensions which are not provided for reference only.

3.2.3.3 Integration. The shelter shall be capable of accepting all integration

configurations of the systems listed in table IV (see 6.2) without modification or

rework to the system integration designs listed in table IV. The shelter shall be

capable of accepting integration configuration cutouts at various locations.

Shelter surfaces shall be capable of accepting the installation of individual

pieces of equipment installed by system integrators at various locations. For

installations where threaded mechanical fasteners are the preferred fasteners, the

attaching surfaces shall be capable of resisting the loads listed in table V for

the listed sizes of threaded mechanical fasteners, without damage or degradation

to the shelter or fastener.
