Presence Sensor Alarm Conditions
The presence sensors for the power supplies and fans indicate that the component is
physically installed. The sensors do not provide status or health of a component.
During the boot process, the management controller looks for presence sensors to
build a list of Oracle ILOM targets. If the presence sensor cannot be read, yet the
component is physically installed, the management controller does not propagate the
component to the list of targets. Even if the component powers up, so long as it is
invisible to the management controller, the component cannot be used.
If a presence sensor alarms while a component is functional, the management
controller functions as if the component were removed from the chassis. This
situation might cause a fault on the component. If the lack of the component violates
a configuration rule, the chassis Attention LED might illuminate.
