Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
If an action step is preceded by "(trained technician only)," that step must be performed only by a trained technician.
LED
Description
Action
Check log LED
An error has occurred and cannot be isolated without performing certain procedures.
Check the IMM2 system event log and the system-error log for information about the error.
Save the log if necessary and clear the log afterwards.
System-error LED
An error has occurred.
Check the light path diagnostics LEDs and follow the instructions.
Check the IMM2 system event log and the system-error log for information about the error.
Save the log if necessary and clear the log afterwards.
PS
When only the PS LED is lit, a power supply has failed.
The system might detect a power supply error. Complete the following steps to correct the problem:
Check the power-supply with a lit yellow LED (see Power-supply LEDs).
Make sure that the power supplies are seated correctly and plugged in a good AC outlet.
Remove one of the power supplies to isolate the failed power supply.
Make sure that both power supplies installed in the server are of the same AC input voltage.
Replace the failed power supply.
PS + CONFIGWhen both the PS and CONFIG LEDs are lit, the power supply configuration is invalid.
If the PS LED and the CONFIG LED are lit, the system issues an invalid power configuration error. Make sure that both power supplies installed in the server are of the same rating or wattage.
OVER SPEC
The system consumption reaches the power supply over-current protection point or the power supplies are damaged.
If the Pwr Rail (A, B, C, D, E, F, G, and H) error was not detected, complete the following steps:
Use the Power Configurator utility to determine current system power consumption. For more information and to download the utility, go to the IBM Power Configurator website.
An error has occurred on a PCI card, a PCI bus, or on the system board. An additional LED is lit next to a failing PCI slot.
Check the riser-card LEDs, the ServeRAID error LED, and the dual-port network adapter error LED to identify the component that caused the error.
Check the system-error log for information about the error.
If you cannot isolate the failing component by using the LEDs and the information in the system-error log, remove one component at a time; and restart the server after each component is removed.
Replace the following components, in the order shown, restarting the server each time:
A nonmaskable interrupt has occurred, or the NMI button was pressed.
Check the system-error log for information about the error.
Restart the server.
CONFIG
CONFIG + PS An invalid power configuration error has occurred.
If the CONFIG LED and the PS LED are lit, the system issues an invalid power configuration error. Make sure that both power supplies installed in the server are of the same rating or wattage.
CONFIG + CPU A hardware configuration error has occurred.
If the CONFIG LED and the CPU LED are lit, complete the following steps to correct the problem:
Check the microprocessors that were just installed to make sure that they are compatible with each other (see Replacing a microprocessor and heat sink for additional information about microprocessor requirements).
(Trained technician only) Replace the incompatible microprocessor.
Check the system-error logs for information about the error. Replace any component that is identified in the error log.
CONFIG + MEM A hardware configuration error has occurred.
When only the CPU LED is lit, a microprocessor has failed.
If the CONFIG LED is not lit, a microprocessor failure occurs, complete the following steps:
(Trained technician only) Make sure that the failing microprocessor and its heat sink, which are indicated by a lit LED on the system board, are installed correctly. See Replacing a microprocessor and heat sink for information about installation and requirements.
CPU + CONFIG When both the CPU LED and the CONFIG LED are lit, the microprocessor configuration is invalid.
If the CONFIG LED and the CPU LED are lit, the system issues an invalid microprocessor configuration error. Complete the following steps to correct the problem:
Check the microprocessors that were just installed to make sure that they are compatible with each other (see Replacing a microprocessor and heat sink for additional information about microprocessor requirements).
(Trained technician only) Replace the incompatible microprocessor.
Check the system-error logs for information about the error. Replace any component that is identified in the error log.
MEM
When only the MEM LED is lit, a memory error has occurred.
Note
Each time you install or remove a DIMM, you must disconnect the server from the power source; then, wait 10 seconds before restarting the server.
If the CONFIG LED is not lit, the system might detect a memory error. Complete the following steps to correct the problem:
A fan has failed, is operating too slowly, or has been removed. The TEMP LED might also be lit.
Check if your server installed with the adapters mentioned in Table 1. If yes, make sure your server compile with the configuration with four fans installed.
Reseat the failing fan, which is indicated by a lit LED near the fan connector on the system board.
