After some digging, I found it:
From command line "setup.exe ENABLEFIPSMODE=1"
Is there any way to tell which mode you are running in currently? Our McAfee admin left unexpectedly and we haven't been able to find any documentation of whether or not he installed in FIPS mode.
In the file system where the ePO files are located, fish out the DB\server.ini file.
There is an entry like fipsmode=1
It should be under Program Files\ePolicy Orchestrator\DB\server.ini...
Thanks tahoekid! i saw your original edit and couldn't find anything in the registry so I emailed McAfee support. They gave me the info below. Figured i'd share it for anyone else who ends up in my shoes some day. Or ends up with the value of "2" and is confused by it
The following additional inspection can be used to identify an ePO environment in FIPS mode.
(a) Server.ini(<EPO install dir>\DB\) -
FipsMode=0 - Server is not running in FIPS mode
FipsMode=1 - Server is running in FIPS mode
FipsMode=2 - Server is in transition mode due to being upgraded from a previous version.
(b) Database - EPOSchemaInfo table
ePOFipsMode - Same values as server.ini FipsMode setting
