Solution Type Problem Resolution Sure Solution 1003523.1 : The Enterprise[TM] 450 system's CPU temperature is not within the acceptable range
PreviouslyPublishedAs 204953 Symptoms The grill in front of the CPU Fan Tray may become clogged with dust causing inefficient cooling and a higher than normal CPU temperature. A thermal error condition may be reported by prtdiag. SunCheckup could report this as follows: CHECK ID: 1478 SEVERITY: HIGH PROBLEM: The Enterprise 450 system's CPU temperature is not within the acceptable range. RECOMMEND: Investigate and schedule diagnostics for the E450 with a Sun Service Representative. Check the airfilters for excessive dirt. The TLP analysis could also include (for example): Check Analysis The E450 CPU's temperature reading is outside of acceptable operating conditions. CPU temperatures must be below 50C. Analysis shows: CPU 1 has a recorded temperature of 53 degrees Celsius CPU 3 has a recorded temperature of 51 degrees Celsius In the Sun Enterprise[TM] 450 Server, a high central processing unit (CPU) temperature and a high CPU fan speed can cause problems even if ambient temperature is low. The system will shutdown if the CPU reaches 80 degrees Celsius . If diagnostics report no problem with the fan tray module or with any other parts of the system, the system may simply be suffering from an accumulation of dust in the air intake path of the CPU fans. Resolution [See the exploded view of the E450 in the System Handbook for designation of parts.]
