System Health LED
This LED indicates the overall health state of the system, including the state of system firmware and the OS. If the LED is amber or red, the system needs attention. Examine the event logs for details of the problem.
The System Health LED performs the following tasks:
•Carries forward the ATTENTION functionality of legacy Integrity and HP 9000 front panel designs
•Indicates whether the server is up or down. External and Internal Health LEDs do not indicate whether the server is booted.
•Covers the wide range of faults for which the software and firmware do not definitively state that a FRU must be reseated or replaced. External and Internal Health LEDs do not light unless the software or firmware makes a solid determination that a FRU must be reseated or replaced.
