Alternating (Invalid FRU) Blink Rate

The alternating (invalid FRU) blink rate is a repeating sequence of lit green and amber indicators at 1 Hz. This indicates that a component has an incorrect version or mismatch, for example, a power supply with a lower rating than the one specified. The blink rate is also used for an unsupported component, or a component in an unsupported slot.
