Visually inspect the power cables and reseat the connectors. 2. Run the following command diag -Avd sysplanar0. When the Resource Repair Action menu displays, select sysplanar0. System shutdown due to loss of ac power to the site. Action: System resumed normal operation, no action required. Power fault due to manual activation of power-off request. Action: Resume normal operation. An over-temperature condition was detected Action: Verify the following: v The room ambient temperature is within the system operating environment v There is unrestricted air flow around the system v All system covers are closed. If all conditions are met, then replace the temperature sensor FRU. System shutdown due to an over maximum temperature condition being reached. Action: Verify the following: v The room ambient temperature is within the system operating environment. v There is unrestricted air flow around the system. v All system covers are closed. If all conditions are met, then replace the temperature sensor FRU. System shutdown due to over temperature condition and fan failure. Use the physical FRU location(s) as the probable cause(s). Action: Use the physical location codes to replace the FRUs that are identified on the diagnostics problem report screen. Sensor detected a voltage outside of the normal range. Action: Use Chapter 4, "Problem determination procedures for AIX and Linux," on page 21. Sensor detected an abnormally high internal temperature. Action: Verify that: 1. The room ambient temperature is within the system operating environment. 2. There is unrestricted air flow around the system. 3. All system covers are closed. 4. There are no fan failures. Sensor detected a voltage outside of the normal range. Use Chapter 4, "Problem determination procedures for AIX and Linux," on page 21. Sensor detected an abnormally high internal temperature. Action: Verify that: 1. The room ambient temperature is within the system operating environment. 2. There is unrestricted air flow around the system. 3. All system covers are closed. 4. There are no fan failures. Platform-specific error. Action: Call your support center. 116 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
