  • The JRE version is not correct.
  • The JRE version is incompatible with the iBMC.
Solution
  1. Check whether the JRE version is correct.

    The iBMC supports JRE 1.7 U45 and JRE 1.8 U45.

    • If yes, go to 3.
    • If no, go to 2.

  2. Install a JRE version supported by iBMC.

    Install JRE 1.7 U45 or 1.8 U45, and go to 3.

  3. Modify Java security configuration.

    1. Check the Java version of the client.

      On the Windows command line interface (CLI) or Linux terminal, run the java –version command.

    2. Open Java Control Panel.
      • In Windows, open Java Control Panel through the Control Panel.
      • In Linux:
        1. Open the client.
        2. Access the Java installation directory, for example, /usr/java/jre1.7/bin.
        3. Open the Java Control Panel.
    3. Solve the incompatibility issue between JRE and the iBMC.

      You can solve the incompatibility issue by modifying the Java security configuration.

      • If the Java version is JRE 1.7 U45, perform the following:
        1. On the Java Control Panel, set the security level to Medium and click OK.
        2. Restart the web browser.
      • If the Java version is JRE 1.8 U45, perform the following:
        1. On the Security tab page, click Edit Site List.
        2. Add the iBMC IP address and the port number (443 by default), for example, https://192.168.2.10:443/, to the list.
