Installing and Replacing the ASA SSM 10/20
This section describes how to install and replace the ASA SSM 10/20 in the adaptive security appliance.
This section includes the following topics:
•Installing an ASA SSM 10/20, page A-9
•Replacing an ASA SSM 10/20, page A-10
There are two types of the SSM: the ASA SSM 10 and the ASA SSM 20. Both types look identical, but
the ASA SSM 20 has a faster processor and more memory than the ASA SSM 10. Only one module (the
ASA SSM 10 or the ASA SSM 20) can populate the slot at a time.
For more information on the ASA SSM 10/20, see the “Assigning Traffic to the SSM” section in the
Cisco Security Appliance Command Line Configuration Guide.
Table A -4 lists the memory specifications for the ASA SSM 10 and the ASA SSM 20.
