I hope you've gotten your answer by now. I just had this same question answered by Cisco. I have two ASA 5510 appliances running in active/standby failover. Each has a CSC module.

Problem Description

If I understand the issue correctly, you need to find out if you need to know if the license is required for the both the CSC module running in failover.

Please notes that you need separate license for both the CSC modules as one license would not work for both.

Please let me know if you need any further assistance on this issue.

If your service request requires urgent attention while I am away, please contact the TAC Hotline number given below.
