The baseboard provides system fault/status LEDs in many areas of the board.  There are fault 
LEDs for each DIMM slot and for each processor, and status LEDs for 5-volt stand-by and 
system state.  Operation of some of these LEDs is dependant upon whether an IMM is installed 
or not.  With on-board platform instrumentation, there is limited diagnostic LED support. 

• 

In systems configured with an IMM, the CPU 1 or CPU 2 led is lit to indicate the processor 
is disabled.  DC-Off or AC Cycle will cause the LED to turn off. 

• 

CPU 1 and 2 LEDs are both lit to indicate the baseboard HW has discovered a 
configuration error. If processor mis-population is detected when using standard on-board 
platform instrumentation, baseboard hardware will illuminate both processor error LEDs. If 
an IMM (Professional or Advanced editions) is used, the Sahalee BMC will generate a 
series of beep codes when this condition is detected and will illuminate the processor 1 
fault LED. An AC cycle will cause the LEDs to turn off. 

• 

DIMM fault LEDs are lit by BIOS whenever BIOS disables a specific DIMM.  

• 

The 5-Volt stand-by LED is always lit when 5-volt stand-by is present. 

• 

The Status LED displays the state of the system. It mirrors the state of the Control Panel 
Status LED. Valid states include: Solid Green, Blinking Green, Blinking Amber, Solid 
Amber, and Off.
