v The server is restarted. v A new error occurs, causing the system-error LED to be lit again. Light path diagnostics LEDs The following table describes the LEDs on the light path diagnostics panel and suggested actions to correct the detected problems. Note: Check the system-error log and BMC log for additional information before replacing a FRU. LED Problem Action None, but An error has occurred and cannot be the diagnosed, or the Advanced System System Management (ASM) processor on the Error LED Remote Supervisor Adapter II SlimLine is lit has failed. The error is not represented by a light path diagnostics LED. Check the system error log for information about the error. OVER SPEC The power supplies are using more power than their maximum rating. Replace the failing power supply, or remove optional devices from the server. PS 1 The power supply in bay 1 has failed. Make sure that the power supply is correctly seated. If the problem remains, replace the failed power supply. PS 2 The power supply in bay 2 has failed. Make sure that the power supply is correctly seated. If the problem remains, replace the failed power supply. CPU A microprocessor has failed. Make sure that the failing microprocessor, which is indicated by a lit LED on the system board, is installed correctly. See "Installing a microprocessor" on page 88 for information about installing a microprocessor. VRM CNFG A hardware configuration error has occurred. If the problem remains, replace the microprocessor (trained service technician only). Not used Check the microprocessors just installed to be sure that they are compatible with each other and with the VRM (see the microprocessor section of the User's Guide for compatiblity requirements). Replace an incompatible microprocessor. MEM NMI S ERR Check the system-error logs for information about the error. Replace any components indicated. When this LED is lit, a memory error has occurred. Replace the failing DIMM, which is indicated by the lit LED on the system board. A hardware error has been reported to 1. See the BMC log or the system-error log for the source of the operating system. the fault. Note: The PCI or MEM LED might also be lit. 2. If the PCI LED is lit, follow the instructions for that LED. 3. If the MEM LED is lit, follow the instructions for that LED. 4. Restart the server. A PCI slot error has occurred. 1. See the BMC log or the system-error log. 2. Replace the failing adapter. 3. (Trained service technician) Replace the system board. Chapter 5. Diagnostics 141
