Clarificaion on NSO version link for TSDN 4.0.0 M3: Hi ,in the confluence page, TSDn 4.0.0 M3 release notes or system install., we dont see the 5.7.2.1 installer.bin file link . can u please update the location for every release if there is change in NCS version. And in the system install, it is mentioned as 5.5.2.9 , it is really confusing having different info in different places."Get the nso-5.5.2.9 bin installer file from CCO" in Since the NSO version is not same for standalone and LSA , Please update this link that reflects the proper NCS version for Standalone and LSA .NSO version for LSA : NSO Version : 5.7.1.1 .please provide the link for installer.bin file for this.And please provide the link for nso-5.7.1.1-tsdn-4.0.0-M3.tar.gz for LSA installation. 
Hi Arun1. Please download the bin installer file from CCO. Below is the path for nso 5.7.2.12. We've deleted that internal system installation page. Please refer to the below link for any installation related information.3. The NSO version is same for standalone and LSA. It's 5.7.2.1 for both of them. We have updated the LSA wiki pages to reflect the same. Please refer to the below link.4. Below is the link for standalone and LSA installation:5. Once you extract the above tar file, you'll see the directories each for standalone and LSA. Below is the structure:<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"><pre class="code-java">$ tar -xf nso-5.7.2.1-tsdn-4.0.0-M3.tar.gz $ cd nso-5.7.2.1-tsdn-4.0.0-M3 $ ls -l -rw-r--r--. 1 cisco ncsadmin 67458 Mar 9 15:18 CHANGES -rwxr-xr-x. 1 cisco ncsadmin 23014 Mar 9 15:18 get_technical_support_data.sh drwxr-xr-x. 5 cisco ncsadmin 76 Mar 9 15:18 tsdn drwxr-xr-x. 4 cisco ncsadmin 46 Mar 9 15:18 tsdn-lsa</pre></div></div>Let us know if you need anything else or we are good to close the ticket.Thanks.Closing the ticket as the required information has been provided.
