Cisco Nexus 9508 Ejector Status Flapping: Line Card Replacement
A Cisco Nexus 9508 repeatedly logged PLATFORM-3-EJECTOR_STAT_CHANGED for Slot 1. The line card remained ok , and ports and communication were normal in the initial checks. Reseating the existing card increased the frequency of the events. After replacement with a spare in the same slot, module and port status were normal and the logs stopped.
The replacement result points to a hardware problem associated with the original line card's ejector detection path. The failed component was not identified, so a defective sensor, contact, or internal circuit remains a hypothesis.
