Event ID Event Severity Event Description 7874 Warning Failure to read data from a UGUY FRUID EEPROM Probable Cause: Attempted access to read the UGUY FRUID EEPROM failed. Recommended Action: If there is only one FRUID that can't be read, replace that FRU as soon as possible. If there are a lot of log entries for different FRUs, suspect the Utilities Board or the Utilities cable to those FRUs. For example, if the failures are all associated with a Master IO Backplane, the failing FRU is probably the Utilities cable to that backplane. SNMP Trap: hpevtUguyEepromRdFail - 7874 in HPIFPTRAP.MIB. 7875 Warning Read EEPROM failed Probable Cause: The 100 pin cable from the Utilities Backplane to the System Backplane is bad, or is not properly connected. Recommended Action: Check and reseat the System Backplane Utilities cable. If this does not resolve the issue, replace the System Backplane utilities cable following the Backplane Utilities Cable Remove and Replace procedures. SNMP Trap: hpevtSysBkpEepromRdFail 7875 in HPIFPTRAP.MIB. 7877 Warning Read command on System Backplane I2C bus failed Probable Cause: The 100 pin cable from the Utilities Backplane to the System Backplane is bad, or is not properly connected. Recommended Action: Check and reseat the System Backplane Utilities cable. If no help, replace the System Backplane utilities cable following the Backplane Utilities Cable Remove and Replace procedures. SNMP Trap: hpevtSysBkpI2cRdFail - 7877 in HPIFPTRAP.MIB. 7878 Warning Write command on System Backplane I2C bus failed Probable Cause: The I2C bus into the System Backplane EEPROM is bad. Recommended Action: Could possibly be a bent pin on the System Backplane Utilities cable connectors. Check the connectors at each end of the cable for bent or broken pins. If the connectors and cable are good, replace the System Backplane following the System Backplane Remove and Replace procedures. NOTE: System Backplane replacement is a major undertaking. Ensure all other possibilities have been explored before replacing the backplane. You should have WTEC approval before replacing the backplane. SNMP Trap: hpevtSysBkpI2cWrFail - 7878 in HPIFPTRAP.MIB. 7879 Error System Backplane Power Fault Probable Cause: While running normally, the CLU microcontroller detected a fault on the I2C Bus from the system Backplane LPM. Recommended Action: Check other log entries around this time for other events. If there are other events, analyze for best troubleshooting approach. Check the log carefully as a shorted ASIC could cause many errors to occur. These errors will not necessarily point to the ASIC. If none, replace failed Backplane Power Board. SNMP Trap: hpevtSysBkpPowerFault - 7879 in HPIFPTRAP.MIB. 7880 Error System Backplane voltage margin failed Probable Cause: The CLU was unable to write to the voltage margin register on the System backplane. Recommended Action: Try re-margining the system backplane and check connections. If many I2C access events are occurring inspect the UGUY utilities board. SNMP Trap: hpevtSysBkpVoltMrgnFail - 7880 in HPIFPTRAP.MIB. 7891 Warning Failure to write data to FRUID EEPROM Probable Cause: The entity being written to has failed. Recommended Action: Replace the entity with the failed FRUID. SNMP Trap: hpevtWriteFruDataFail - 7891 in HPIFPTRAP.MIB. 7892 Error CPU fan failed Probable Cause: The CPU fan identified by the attached physical location has failed. Recommended Action: Contact HP Support personnel to troubleshoot problem SNMP Trap: hpevtCpuFanFail - 7892 in HPIFPTRAP.MIB. 7893 Warning CPU fan failing Probable Cause: The CPU fan identified by the attached physical location is not operating at expected speed. Recommended Action: Contact HP Support personnel to troubleshoot problem SNMP Trap: hpevtCpuFanSlow - 7893 in HPIFPTRAP.MIB. 7894 Error CC chip fan failed Probable Cause: The CC chip fan identified by the attached physical location has failed. Recommended Action: Contact HP Support personnel to troubleshoot problem SNMP Trap: hpevtDnaFanFail - 7894 in HPIFPTRAP.MIB. 7895 Warning CC chip fan failing Probable Cause: The CC chip fan identified by the attached physical location is not operating at expected speed. Recommended Action: Contact HP Support personnel to troubleshoot problem SNMP Trap: hpevtDnaFanSlow 7895 in HPIFPTRAP.MIB. Platform Agent Events 45
