System-event log
The system-event log contains messages of three types:
Information
Information messages do not require action; they record significant
system-level events, such as when the server is started.
Warning
Warning messages do not require immediate action; they indicate possible
problems, such as when the recommended maximum ambient temperature
is exceeded.
Error Error messages might require action; they indicate system errors, such as
when a fan is not detected.
Each message contains date and time information, and it indicates the source of
the message (POST or the IMM).
Integrated management module error messages
The following table describes the IMM error messages and suggested actions to
correct the detected problems. For more information about IMM, see the
Integrated
Management Module User's Guide at http://www.ibm.com/systems/support/
supportsite.wss/docdisplay?lndocid=MIGR-5079770&brandind=5000008.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v
See Chapter 4, “Parts listing, System x3400 M3 Types 7378 and 7379,” on page 141 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.
Message Severity Description Action
Numeric sensor Ambient Temp going
high (upper critical) has asserted. Error An upper critical sensor
going high has asserted. Reduce the ambient temperature.
Numeric sensor Ambient Temp going
high (upper non-recoverable) has
asserted. Error An upper nonrecoverable
sensor going high has
asserted. Reduce the ambient temperature.
Numeric sensor Planar 3.3V going
low (lower critical) has asserted. Error A lower critical sensor going
low has asserted. (Trained service technician only)
Replace the system board.
Numeric sensor Planar 3.3V going
high (upper critical) has asserted. Error An upper critical sensor
going high has asserted. (Trained service technician only)
Replace the system board.
Numeric sensor Planar 5V going low
(lower critical) has asserted. Error A lower critical sensor going
low has asserted. (Trained service technician only)
Replace the system board.
Numeric sensor Planar 5V going high
(upper critical) has asserted. Error An upper critical sensor
going high has asserted. (Trained service technician only)
Replace the system board.
Numeric sensor Planar VBAT going
low (lower critical) has asserted. Error A lower critical sensor going
low has asserted. Replace the 3 V battery.
Numeric sensor Fan n Tach going
low (lower critical) has asserted.
(
n = fan number)
Error A lower critical sensor going
low has asserted.
1. Reseat the failing fan n , which
is indicated by a lit LED on
the fan.
2. Replace the failing fan.
( n = fan number)
