When the system maintenance switch position 6 is set to the On position, the system is prepared to erase

configure the server or data loss could occur.
Internal system health LED combinations
When the internal system health LED on the front panel ("Front panel LEDs and buttons" on page 77)
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.
