System-event logThe system-event log contains messages of three types:InformationInformation messages do not require action; they record significantsystem-level events, such as when the server is started.WarningWarning messages do not require immediate action; they indicate possibleproblems, such as when the recommended maximum ambient temperatureis exceeded.Error Error messages might require action; they indicate system errors, such aswhen a fan is not detected.Each message contains date and time information, and it indicates the source ofthe message (POST or the IMM).Integrated management module (IMM) error messagesThe following table describes the IMM error messages and suggested actions tocorrect the detected problems. For more information about IMM, see the IntegratedManagement Module User's Guide at http://www.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=MIGR-5079770&brandind=5000008v 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 x3250 M3 Types 4251, 4252, and 4261,” on page 119 to determinewhich components are customer replaceable units (CRU) and which components are field replaceableunits (FRU).v If an action step is preceded by “(Trained service technician only),” that step must be performed only by atrained service technician.Message Severity Description ActionNumeric sensor Ambient Tempgoing high (upper critical) hasasserted.Error An upper critical sensorgoing high has asserted.Reduce the ambient temperature.Numeric sensor Ambient Tempgoing high (upper non-recoverable)has asserted.Error An upper nonrecoverablesensor going high hasasserted.Reduce the ambient temperature.Numeric sensor Planar 3.3V goinglow (lower critical) has asserted.Error A lower critical sensor goinglow has asserted.(Trained service technician only)Replace the system board.Numeric sensor Planar 3.3V goinghigh (upper critical) has asserted.Error An upper critical sensorgoing high has asserted.(Trained service technician only)Replace the system board.Numeric sensor Planar 5V goinglow (lower critical) has asserted.Error A lower critical sensor goinglow has asserted.(Trained service technician only)Replace the system board.Numeric sensor Planar 5V goinghigh (upper critical) has asserted.Error An upper critical sensorgoing high has asserted.(Trained service technician only)Replace the system board.Numeric sensor Planar VBAT goinglow (lower critical) has asserted.Error A lower critical sensor goinglow has asserted.Replace the 3 V battery.Chapter 3.
