Microprocessor problemsIdentify microprocessor problem symptoms and what corrective actions to take.v Follow the suggested actions in the order in which they are listed in the Action column until the problem issolved.v See Chapter 3, “Parts listing, Type 8406,” on page 229 to determine which components are CRUs and whichcomponents are FRUs.v If an action step is preceded by “(Trained service technician only),” that step must be performed only by atrained service technician.Symptom ActionThe blade server will not bootor a checkpoint or firmwareerror code is logged in themanagement-module event log(the startup microprocessor isnot working correctly)1. If a checkpoint or firmware error was logged in the Advanced ManagementModule event log, correct that error.2. If no error was logged, restart the blade server and check the managementmodule event log again for error codes.3. Replace the system-board.Network connection problemsIdentify network connection problem symptoms and what corrective actions to take.v Follow the suggested actions in the order in which they are listed in the Action column until the problem issolved.v See Chapter 3, “Parts listing, Type 8406,” on page 229 to determine which components are CRUs and whichcomponents are FRUs.v If an action step is preceded by “(Trained service technician only),” that step must be performed only by atrained service technician.Symptom ActionOne or more blade servers areunable to communicate withthe network.1. Verify that the I/O module is a switch or pass thru module. Ppass thrumodules require an upstream switch for network traffic to pass.2. Ensure the correct device drivers are installed.3. Verify that the optional I/O expansion cards are correctly installed andconfigured, see “Removing and installing an I/O expansion card” on page 246PCI expansion card (PIOCARD) problem isolation procedureThe hardware that controls PCI adapters and PCI card slots detected an error. The direct select address(DSA) portion of the system reference code (SRC) identifies the location code of the failing component.194 Power Systems: Problem Determination and Service Guide for the IBM Power PS700 (8406-70Y)
