Installation Instructions for F5 BIG-IP Load balancer version 9.x and 10.x


To install RapidSSL certificate for Big-IP F5 Version 9.x and 10.x, please follow the steps below. If you are unable to use these instructions for your server, RapidSSL recommends that you contact either the vendor of your software or an organization that supports F5 BIG-IP server.

Step 1: Obtain the RapidSSL certificate and intermediate CA certificate

    1.    The RapidSSL certificate download link will be sent by email.

    2.    Download and extract the certificate zip file from the email. 

           NOTE: Click here for steps to download the RapidSSL certificate.

    3.  If you do not have the intermediate, it can be downloaded from this link

    4.    Save the files to the following location: /config/bigconfig/ssl.crt/

           NOTE: In a redundant system, the keys and certificates must be in place on both controllers
           before you configure the SSL Accelerator. You must do this manually as the configuration
           synchronization utilities do not perform this function.

 Step 2: Install the Intermediate CA certificate

    1.    Log in to the Configuration utility.

    2.    Click Local Traffic.

    3.    Click SSL Certificates.

  4.    Click Import

  5.    Select Certificate from the Import Type menu.

    6.    Click the Create New option.

    7.    Type a unique name for the Certificate Name.

    8.    Click Browse and navigate to the file you saved as intermediate_ca.crt.

    9.    Click Open.

  10.    Click Import.  


Step 3: Install the RapidSSL Certificate


    1.    In the navigation pane, click Proxies.

    2.    On Proxies screen, click the Install SSL Certificate Request tab. 
           The Install SSL Certificate screen opens.

    3.    In the Certfile Name box, enter the fully qualified domain name of the server with
           the file extension .crt. If you generated a temporary certificate when you submitted
           a request to RapidSSL, you can select the name of the certificate from the drop down
           list. This allows you to overwrite the temporary certificate with the new one.
    4.    Paste the text of the certificate into the Install SSL Certificate window. 

    5.    Click Write Certificate File to install the certificate. After the certificate is installed, 
           you can continue with the next step in creating an SSL gateway for the server.

Step 4: Establish the Trust Chain          

    1.    Log in to the Configuration utility. 

    2.    Click Local Traffic.

    3.    Click Profiles.

    4.    Select Server from the SSL menu.

    5.    Select the Server SSL profile to configure.

    6.    Select Advanced from the Configuration menu.

    7.    Select the appropriate chain certificate from the Chain dropdown box.

    8.    Click Update.
           NOTE: Please refer to the screenshot of the F5 Big-IP interface


     9.    Verify your installation with the RapidSSL Checker
