What should a field engineer do about C0040004?

The manual states the board may be broken. Check that the DTB is seated in its cPCI slot with power and backplane connections intact and retry initialization; if it still cannot initialize, replace the DTB.. Isolate the RTM — ISP / Fibre Channel link 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.
