What should a field engineer do about C0900004?

The real-time reconstruction setup command went unanswered. Check the reconstruction path (the MHR boards in the REC BOX and the GLINK connections between them) for a communication or timing fault: review the event log, confirm the MHR boards are running, and run the MHR hardware test before rescanning.. Isolate the RTM — ELCTL (pre-process / recon control) subsystem and follow the status-code troubleshooting in the service manual. FSELIB documents the full diagnosis and remedy for the Aquilion RX / V4-62R004 / V3.20R003 / Aquilion ONE / V4.2 / Aquilion S16 / Asteion Super4 / Aquilion 16.
