The server logs OEM-specific BIOS messages in the BMC system-event log. The following table describes the four BIOS sensor types logged in the BMC system-event log. You can obtain third-party software to provide BMC system-event log translations for detailed byte definitions and repair actions. v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v SeeChapter 4, "Parts listing, System x3655, Type 7985," on page 97 to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician.
