If a DIMM or processor fails, the front panel Service Action Required LED lights. A lit Service Action Required LED indicates that immediate service action is required. You can use the internal DIMM or processor test circuit to identify the failed DIMM or processor component. Remove the server module from the server, open the top cover, and press the DIMM or processor test circuit Fault Remind button on the motherboard as soon as possible.
The test circuitry power charge has a time-limited window of usability (30–60 minutes). When the Fault Remind button is pressed, a Charge Status LED lights if the circuit is usable. If too much time has elapsed between removing the server module and viewing the test circuit LEDs, the charge can discharge completely. If the test circuit charge is completely depleted, the test circuit becomes unusable, the Charge Status LED turns off, and the Fault Remind error information is lost. To use the test circuit again, install the server module into the chassis, and let the error occur again.
For more information about how to identify faulty DIMMs or processors using on-board fault test circuits, see:
The server's processor provides data parity protection on its internal cache memories and error-correction code (ECC) protection. The system can detect the following types of errors: correctable and uncorrectable memory ECC errors and uncorrectable processor internal errors. Errors are recorded in the Oracle ILOM system event log (SEL).
Advanced ECC corrects up to 4 bits in error on nibble boundaries, as long as they are all in the same DRAM. If a DRAM fails, the DDR3 DIMM continues to function. For instructions for clearing DDR3 DIMM faults, refer to the Sun Blade X3-2B (formerly Sun Blade X6270 M3) Administration Guide.
