Table 5-7 Internal Health LED States
LED Color
Flash Rate
Definition
LED off
Health good on all internal CRUs and system off.
Green
Steady
Health good on all internal CRUs, and system firmware has
passed “BOOT_START”.
Amber
Flash 1 Hz
An internally accessible CRU failed (system is on or in standby
mode). Check the System Insight Display or internal system
LEDs.
The internal health LED clears once all of the LEDs on the diagnostic LED panel have been
cleared. For details on how each LED in the System Insight Display is cleared, see
“System Insight
Display LEDs” (page 116)
; also see the respective system specification for the server in question.
Events that cause each internal CRU (or System Insight Display) LED to light are listed in the
CRU section.
Amber supersedes green. This LED is cleared when all failed internally accessible entities are
repaired and report that they are good, or on any ac/standby power cycle.
NOTE:
The LEDs are cleared on the System Insight Display by turning off, not by turning green.
The iLO 2 MP displays the following strings in its Virtual Front Panel for the three states of this
LED:

Off
Internal parts, including CPUs and memory, okay
On Green
An internally accessible CRU failed: check System Insight Display

System Health LED
The rx2660 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 (external and internal
health LEDs do 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 amber or red, the system needs attention, and the event logs should be
examined for details of the problem.

LED Off
System is off, or system is booting firmware with no failures, since SEL logs
last examined.

System has left the firmware boot, and an OS is booting or running with no
failures, since SEL logs last examined.
Amber
Flash 1 Hz
A warning or critical failure has been detected and logged.
