System LEDs and internal health LED combinations
When the internal health LED on the front panel illuminates either amber or red, the server is experiencing
a health event. Combinations of illuminated system LEDs and the internal health LED indicate system
status.
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.
