HPE ProLiant Pre-boot Health Summary

If the node will not start up, you can use iLO to display diagnostic information on an external monitor. This feature is supported on node s that support external video and have a UID button or an SUV connector. When power is available to the node but the node is not powered on, iLO runs on auxiliary power and can take control of the node video adapter to display the HPE ProLiant Pre-boot Health Summary.
