Just to close off this unanswered question, you can get into that state (FSM_FT_STATE_STANDBY_COLD) if you have an active and standby ACE and you upload a new cert and/or key and forget to import the cert and/or key to the standby ACE. Then if you save the config the active and standby don't have an identical list of certs and/or keys and it goes into COLD state.
To fix, upload the missing certs and/or keys in appropriate context on the standby ACE, change to the context that should be active (on the active ACE), and type the following and save the config:
conf t
no ft auto-sync running-config
ft auto-sync running-config
exit
wr mem
