LED Indicators and Switches
System LEDs and Internal Health LED Status Combinations
When the internal health LED on the front panel illuminates either amber or red, the server is
experiencing a health event. The combinations of illuminated system LEDs and the internal
health LED in Table 4-8 indicate system status.
NOTE: The system management driver must be installed in order for the internal health LED to provide
pre-failure and system conditions.
The internal health LEDs on the front panel indicate the current hardware status and are used
to assist in initial troubleshooting. Note that in some situations, Insight Manager 7 reports
server status differently than the health LEDs because it tracks more system attributes.
