Intel® Server Board S2600CP and Server System P4000CP TPS Intel® Server Board S2600CP and Intel® Server System P4000CP Platform Management Offset 02h 03h 06h Description Predictive failure - Asserted if some condition, such as failing fan, has been detected that is likely to lead to a power supply module failure. The following codes for warning modes are put into the SEL Event Data 2 byte:  01h - Output voltage warning  02h - Output power warning  03h - Output over-current warning  04h - Over-temperature warning  05h - Fan warning  06h - Under-voltage warning  07h - Input over-current warning  08h - Input over-power warning The SEL Event Data 3 byte will have the contents of the associated PMBus* Status register to allow for showing multiple conditions for the event. For example, Data 3 will have the contents of the VOLTAGE_STATUS register at the time an Output Voltage Warning was detected. Refer to the PMBus Specification for details on specific resister contents. Power supply AC lost - Asserted if there is no AC power input to power supply module. Configuration error - The following codes for configuration errors are put into the SEL Event Data 2 byte:  01h - The BMC cannot access the PMBus* device on the PSU but its FRU device is responding.  02h - The PMBUS_REVISION command returns a version number that is not supported (only version 1.1 and 1.2 are supported for platforms covered under this FW EAS).  03h - The PMBus* device does not successfully respond to the PMBUS_REVISION command.  04h - The PSU is incompatible with one or more PSUs that are present in the system. 05h -The PSU FW is operating in a degraded mode (likely due to a failed firmware update). Event Logging Assertion and Deassertion Assertion and Deassertion Assertion and Deassertion 6.3.8 System Event Sensor The BMC supports a System Event sensor and logs SEL event for following events. Table 20. Support System Event Sensor Offsets Offset Description 02h OEM code (Undetermined system HW failure) 04h PEF action Event Logging Assertion and Deassertion Assertion only For offset 2, OEM code will be logged in event data byte 2 to indicate the type of failure. Only one value will be supported at this time, but others may be added in the future. The code for this particular fault will be 0x00 (PECI access failure) and all other values reserved. Upon detection of the CPU PECI fault condition, the offset shall assert. It shall deassert upon system power cycle or system reset. Assertion of offset 02h shall contribute a "fatal" condition to the system status as reflected in the Front Panel system status LED. Revision 1.2 71 Intel order number G26942-003
