Hi,
I suggest that you consult the configuration guide on failover:
http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/ha_overview.html#wp1126249
The hardware requirement for High Availability is that:
"The two units in a failover configuration must be the same model, have the same number and types of interfaces, the same SSMs installed (if any), and the same RAM installed."
Therefore you will need either AIP in both or a CSC in both.
Having different SSMs in the two ASAs as you have listed above is not a supported configuration.

Sean,
Because ASA 5510 supports just 1 expansion slot. So might be I have to choose 1 of 2 SSMs to use or go for higher model in 5500 Series.
Thanks for your reply
Regards,
Tuan
