https://community.cisco.com/t5/network-security/cisco-asa-versions/m-p/2620184#M195754 <P>Does anyone happen to know where to find information regarding the different hardware (not software) versions for the ASA? Specifically, I currently have an ASA 5505 hardware version 05. What's the difference between that and an ASA 5505 version 09? Or 12?</P><P># sho inventory<BR />Name: "Chassis", DESCR: "ASA 5505 Adaptive Security Appliance"<BR />PID: ASA5505&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; , VID: V05</P> Tue, 12 Mar 2019 05:40:37 GMT Keith Wood 2019-03-12T05:40:37Z https://community.cisco.com/t5/network-security/cisco-asa-versions/m-p/2620184#M195754 <P>Does anyone happen to know where to find information regarding the different hardware (not software) versions for the ASA?

But it's quite common in the industry to optimize a product after the first hardware design, very often just to reduce cost in the production-process.</P> Sun, 22 Mar 2015 12:47:03 GMT https://community.cisco.com/t5/network-security/cisco-asa-versions/m-p/2620185#M195755 Karsten Iwen 2015-03-22T12:47:03Z
