IBM 7985 Problem Determination And Service Manual

v Follow the suggested actions in the order in which they are listed in the Action column until the problemis solved.v See Chapter 4, “Parts listing, System x3655, Type 7985 and 7943,” on page 93 to determine whichcomponents 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 atrained service technician.BMC log messageSensornumberSensortype ActionABR status 8F 0F Information onlyCPU 1 statusAssertion 01 (Thermaltrip)90 07 Information only; if the message remains:1.
