HP SUM User Interface 61
If the user has not changed the default option or has selected Upload and Activate, a warning message
displays, indicating that HP SUM will reboot the server during the firmware update process.
To continue the update, press OK.
You can deploy the Online System, FPGA, iLO-3 MP and Power Monitor firmware using CLI in silent
mode. However, you cannot specify the Upload and Do not Activate mode using CLI. Only the default
Update and Activate mode is available and no parameter is required.
