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.
