HPE ProLiant Pre-boot Health Summary
If the server will not start up, you can use iLO to display diagnostic information on an external monitor. This
feature is supported on servers that support external video and have a UID button or an SUV connector.
When power is available to the server but the server is not powered on, iLO runs on auxiliary power and can
take control of the server video adapter to display the HPE ProLiant Pre-boot Health Summary.
For additional information, see the following documents:
• iLO 4 User Guide — See the Hewlett Packard Enterprise website .
• ProLiant Gen9 Troubleshooting Guide, Volume I: Troubleshooting — See Troubleshooting resources .

event with one-minute granularity.
You can view recorded events in the IML in several ways, including the following:
• From within HPE SIM
• From within the UEFI System Utilities
