The combinations of illuminated system board LEDs and the internal health LED in Table E-7 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 system 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.
