Server component identification 15 NOTE: The system management driver must be installed in order for the internal 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 ("Array Diagnostic Utility" on page 72, "HP Insight Diagnostics" on page 72) may report server status differently than the health LEDs because the software tracks more system attributes.
