ILOM supports two types of system indicator states: Customer Changeable and System Assigned.
Customer Changeable States – Some system indicator LEDs in ILOM offer customer changeable states. Typically, these types of system indicators provide operational states of various system components. The type of states presented is determined by the system indicator. For example, depending on the system indicator, the following customer changeable states might be present:
Off – Normal operating status. Service is not required.
Fast Blink – Helps locate system in a data center.
For more information about viewing and managing system indicators from the ILOM web interface or CLI, see View and Manage Indicators Using the Web Interface or View and Manage Indicators Using the CLI.
System Assigned States – System assigned indicators are not customer configurable. These types of system indicators provide read-only values about the operational state of a component. On most Sun server platforms, system assigned indicators are Service Action Required LEDs. These types of LEDs are typically illuminated when any of the following conditions are detected:
Fault or error is detected on a system component.
Hot-plug module is ready for removal.
Field-replaceable unit (FRU) requires service.
