I need to upgrade two ASA 5505 to version 8.4, for which I bought memory kits to take them to 512K</P><P>The strange thing is neither of them take the memory. One get all light flashing right after booting, and the other one gets into a booting cycle. I have 2 memory kits, and both produce same result. I even RMA'd one of them, and same thing with the new one received.</P><P>I've noticed one says it's ASA 5505 V2, while the other one says ASA 5505 V04</P><P>Is there any hardware restriction to upgrade to 512MB on ASA 5505? Any tool to check with serial number if they can be upgraded or not?</P><P>I'll appreciate any info</P><P>&nbsp;</P><P>Regards</P> Tue, 12 Mar 2019 04:11:36 GMT https://community.cisco.com/t5/network-security/asa-5505-memory-upgrade/m-p/2479782#M238515 Gustavo Villegas 2019-03-12T04:11:36Z https://community.cisco.com/t5/network-security/asa-5505-memory-upgrade/m-p/2479783#M238516 <P>There should not be any restriction as to which hardware minor revision you have.
