v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 8864," on page 23 to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)", that step must be performed only by a trained service technician. System-error log message Action VRM X Power Good Fault 1. Reseat VRM 3 or 4. 2. Reseat the microprocessor tray. 3. Replace VRM 3 or 4. 4. (Trained service technician only) Replace the microprocessor tray. Vtt Power Good Fault 1. Reseat the microprocessor tray. 2. (Trained service technician only) Reseat the microprocessors. 3. Reseat the microprocessor VRMs, if present. 4. (Trained service technician only) Replace the microprocessor tray. POST and SMI error messages BIOS can log two types of error messages in the BMC log and the system-error log: POST events, which occur during system startup, and SMI events, which are generally run time errors detected by hardware. The following table describes the possible POST and SMI error messages and suggested actions to correct the detected problems. v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 8864," on page 23 to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)", that step must be performed only by a trained service technician. Error message Action POST reporting Processor Event: Invalid configuration of processor card. Chassis Number = X. Make sure that all microprocessors have the same part number. POST reporting Processor Event: Processor mismatch detected. Chassis Number = X. Processor Number = Y. 1. Make sure that the BIOS code is at the latest level. 2. Make sure that all microprocessors have the same part number. 3. (Trained service technician only) Replace the microprocessor. POST reporting Processor Event: POST does not support current stepping of processor. Chassis Number = X, Processor Number = Y. 1. Make sure that the BIOS code is at the latest level. 2. Make sure that all microprocessors have the same part number. 3. (Trained service technician only) Replace the microprocessor. POST reporting Processor Event: Unable to apply microcode (patch) update. Chassis Number = X. Processor Number = Y. (Trained service technician only) Replace the microprocessor. 142 IBM System x3850 Type 8864: Problem Determination and Service Guide
