Memory Installation Steps
Depending on the software version and feature license installed on the PIX 515/515E security appliance,
you might need to upgrade the system memory to run newer software versions or more robust software
features.
PIX software Version 6.3 and previous software releases require a minimum of 32 MB of memory with
the Restricted license, and 64 MB of memory with the Unrestricted and Failover licenses.
PIX software Version 7.0 requires a minimum of 64 MB of memory with the Restricted license, and
128 MB of memory with the Unrestricted and Failover licenses.
If you want to upgrade the feature license from Restricted to Unrestricted or Failover, or upgrade the
software from Version 6.3 to Version 7.0, you need to upgrade the memory.
Note
Software Version 7.0 is supported only on the PIX 515/515E security appliance. New PIX 515E security
appliances shipped after the general availability of PIX software Version 7.0 have enough memory to run
version 7.0 and the software license ordered.
