status display also starts over with a reboot or a power cycle with a few exceptions, indicated in Table 22.
Event sensor status indicator descriptions
Gray indicator:
v FRU not plugged
v Sensor not initialized
v Sensor function is not initialized
Red (faulty) indicator:
v Critical threshold exceeded (an event requires a service action)
v Service action required for hard fail
v Partial function failure that reached a "service action required" state
v A deconfigured resource requires service action
Green (good) indicator:
v FRU or sensor is plugged in and fully operational
v Recoverable event is below the critical "service action required" threshold
v FRU or sensor returned to "normal" operating range (for threshold sensors)
Sensor state values during boot process
The key stages of operation.
Initial power on to BMC ready state
In this stage, some indicator values might not reflect the status of the physical sensor. In some
instances, the state is not available because the sensor is not initialized; in this case, the sensor
color is gray. In other cases (typically associated with Host Boot sensors), the value of the sensor
shows the state when the system was operational. These sensors update to indicate the current
status if the display is refreshed when the system reaches the Petitboot stage of operation.
Table 22 shows the affected indicators.
BMC ready to PetitBoot or Host operation state
When the system reaches the Petitboot menu stage, and you refresh the display, all of the
indicators reflect their operational state.
