HP ProLiant ML350 Gen9 - UID Button Functionality; Front Panel Leds Power Fault Codes; Rear Panel Components

Component identification 80
When all four LEDs described in this table flash simultaneously, a power fault has occurred. For more
information, see "Front panel LED power fault codes ("Front panel LEDs power fault codes" on page 80)."
UID button functionality
The UID button can be used to display the HPE ProLiant Pre-boot Health Summary when the server will
not power on. For more information, see the HPE iLO 4 User Guide on the Hewlett Packard Enterprise
website (http://www.hpe.com/info/ilo/docs).
