System Event Log LED
The server has this LED for the following reasons:
•
To carry forward the ATTENTION functionality of legacy Integrity and HP9000 front panel
designs
•
To give the customer an indication of whether the system is up or down (the health LED does
not tell the user if the system is booted.)
•
To cover the wide range of faults for which software/firmware is not 100% sure that a CRU
must be re-seated/replaced. (external and internal health LEDs do not light unless
software/firmware can make a solid determination that a CRU must be re-seated/replaced.)
This LED indicates the overall health state of the system, including the state of system firmware and
the OS. If the LED is red, the system needs attention, and the event logs should be examined for
details of the problem.
