Internal system health LED combinations
When the internal system health LED on the front panel ("Front panel LEDs and buttons" on page 79)
illuminates either amber or red, the server is experiencing a health event. Combinations of illuminated HP
Systems Insight Display LEDs and the internal health LED indicate system status.
NOTE: The system management driver must be installed for the internal system health LED to
provide pre-failure and warranty conditions.
The front panel health LEDs indicate only the current hardware status. In some situations, HP SIM may report
server status differently than the health LEDs because the software tracks more system attributes.
