Off
System power is on; externally serviceable components (usually
accessible from front or back, such as fans and power supplies) are
okay.
Steady
Green
An externally accessible CRU failed (system is on or in standby mode).
Usually, this is a power supply or fan failure. Check front/back LEDs for
failed component.
Flash 1 Hz
Amber
Amber supersedes green. This LED is cleared when all failed externally accessible entities are
repaired and report that they are good, or on any AC/standby power cycle.

Internal Health LED (IHLED)
The required front panel Internally Serviceable Server Health LED, called Internal Health LED,
indicates the status of the components internal to the system chassis. These components require
the user to open the system in order to be serviced. This LED will maintain its state when the
system is in standby mode (system power turned off but AC power still applied to the system).
On larger Integrity servers that have a Diagnostic LED board, this LED tells the service person
that she/he should view that board for more information about the server failure. If the Internal
Health LED is green, there is no fault information displayed on the Diagnostic LED board, and
no fault information displayed on LEDs that are inside the server.
The amber indicators on this LED must correspond to internal health conditions that will light
other LEDs in the box, indicating which component must be serviced to correct the fault. For
example, the Diagnostic LED board will have a fault indicator lit when this LED is in the Amber
condition. Failures that cause the Internal Health LED to light will not cause the External Health
LED to light.

The internal health LED will clear once all of the LEDs on the Diagnostic LED panel have been
cleared. For details on how each LED in the Diagnostic panel is cleared, see
; also see the respective system specification for the server in question. Events
that cause each internal FRU (or Diagnostic Panel) LED to light are listed in the FRU 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.
