In addition to issuing SSL Certificates, a Trusted Root CA certificate can also be used to create another certificate, which in turn can be used to issue SSL Certificates. The majority of SSL certificates in use around the world are chained certificates of this type.

As the Intermediate Certificate is issued by the Trusted Root CA, any SSL Certificates issued by the Intermediate Certificate inherits the trust of the Trusted Root, effectively creating a certification chain of trust. In many cases the chaining is not limited to a single intermediate. More than one intermediate certificate may be part of a Certificates Bundle.

To upload the CA chain certificate:

  1. Log in to the Admin UI using your System Console account.

    For more information, see Logging in to the Admin Portal.

  2. Navigate to MAINTENANCE > SECURITY.

  3. Click the Server Cert subtab.


  4. Click Upload CA Chain Certificate.

    The Upload CA Chain Certificate pop-up displays.

  5. Click Choose File to locate the file.

  6. Click Upload.

    A Confirmation pop-up displays.

  7. Click Yes.
