CauseThe temperature is erroneously reported, due to a problem with a board sensor.SolutionReplace the system board.Product Sun Fire E20K Server Sun Fire 15K Server Sun Fire 12K Server Sun Fire E25K Server Internal Comments For Oracle/Sun internal use only. This is not the real temperature of the processor; it is bug 5030969 The temperature reported is the power on default value wrongly interpreted by SMS as a legal value. The sensor in question can only report temperatures between 0C and 127C When receiving a value of -128C or 128C, SMS should report an error (because of an illegal value) and not take incorrect actions. Most of the units using this sensor have been screened out but it is possible that a small number still exist at customer locations The fix required a change in the temperature circuit so the system board must be replaced.
