I can find documents detailing FIPS 140-2 configuration for FOS v7.3 and before, but not much after that point. Has FIPS-compliant configuration changed any since v7.3? One would think it has over the last 2 years and 2 release levels. Key sizes and hash algorithms have certainly gotten longer in the real world.
for FOS 8.x you can find details about FIPS in the Command Reference Manuals
the same for FOS 7.4
