This reports the current state of the node's front-panel fault, or service, LED as off, on, or blinking, applicable to 6520 platforms. Unlike the general status LED, this one specifically flags a fault or service-needed condition, so an admin remotely seeing this LED reported as on or blinking should treat it as a stronger signal than the status LED alone that the node needs physical attention, even before drilling into the more granular hardware-status objects elsewhere in this MIB. For example, this LED reporting on while the general status LED reports normal operation would still be the more urgent signal, indicating a fault condition needing service despite the node otherwise appearing operational.
