Hi Perkins,
Yes. We have all set to use ASA 5500 series appliances as a FIPS -140-2 Compliant. But you have use the settings defined for FIPS compliance like it should be in single context mode, asa should be in routed mode, fips has to be enabled, password recovery has to be disabled, register value has to be set to skip the rommon mode while booting.... etc.
Please check for the latest IOS which is approved by FIPS.
Please do rate if the given information helps.
