Memory Fault Indication LEDs
The memory fault LEDs provide visual notification to a service technician which memory
DIMM slot(s) are at fault due to un-correctable memory errors during POST (Power-On Self-
Test). A memory fault LED will remain "on" even after system reboots (or repeated "power
cycling") until it is reset manually by the technician using the BIOS setup menu to turn it off.
This feature allows the technician to easily identify and replace any bad DIMMs that may be
at fault in the system.
