MS-9246 1U Rackmount Server

™Diagnostic LEDs: DLED1/DLED2/DLED3/DLED4 Memory LEDs:D29/D30/D31/D32/D33/D35

Component LEDs and four Diagnostic LEDs are integrated onboard, helping users diagnose their systems.

When POST or Service Processor detects an error, the corresponding LEDs light up to alert users to the condition and help service personnel identify the failing component. A system status LED on the front panel of the system first alerts users that an error has occurred. Service personnel next check in- side the system to see which LED glows. This helps the service personnel to locate the failing component for replacement. The full failing path remians lit until POST no longer exists or the error is fixed.

The four Diagnostic LEDs can detect all problems that fail the system, such as VGA, RAM or other failures, and provide up to 16 combinations of signals to debug the system. Please refer to the following table for signal description.
