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.
Table 44 displays information about the Internal Health LED states.

repaired and report that they are good, or on any AC/standby power cycle.
