ASA 5505 with 256 MB DRAM—Starting in Version 8.3, the DRAM requirements for the ASA 5505 were
increased to 512 MB. If you did not use the Unlimited Hosts license or the Security Plus license with failover
enabled, then the ASA could continue to operate with 256 MB. As of Version 9.2 and later, all ASA 5505
licenses require 512 MB. If you only have 256 MB, the ASA image may not load into memory. See

Upgrade impact for ASDM login when upgrading from a pre-9.2(2.4) release to 9.2(2.4) or later—If you
upgrade from a pre-9.2(2.4) release to ASA Version 9.2(2.4) or later and you use command authorization and
ASDM-defined user roles, users with Read Only access will not be able to log in to ASDM. You must change
the more command either before or after you upgrade to be at privilege level 5; only Admin level users can
make this change. Note that ASDM version 7.3(2) and later includes the more command at level 5 for defined
user roles, but preexisting configurations need to be fixed manually.

ASDM:

Choose Configuration > Device Management > Users/AAA > AAA Access > Authorization, and click
Configure Command Privileges.

Select more, and click Edit.

Change the Privilege Level to 5, and click OK.
