Component-Specific LEDs

This table lists component-specific fault LEDs that light when the component requires service. You can use these LEDs to help locate a component that the fmadm faulty command reports as faulty. Where indicated, these components also display blue Ready to Remove LEDs that must light before you can remove the component.


Note -  Component LEDs might not be lit when the component is faulty. Rely on software to determine if a component is faulty. See Checking for Faults.
