Troubleshooting Hardware Faults Using Oracle ILOM
Alternating (Invalid FRU) Blink Rate
A repeating sequence of lit green and amber indicators at 1 Hz. Indicates that a component has
an incorrect version or mismatch (for example, a power supply with a lower rating than the one
specified). Also used for an unsupported component, a component in an unsupported slot, or a
blade (server module) that causes a power supply to be oversubscribed for that system.
