10.6 Fan Fault LEDs
The server board includes a Fan Fault LED next to each of the six system fans and both CPU
fans. The LED has two states: On and Off. The BMC lights a fan fault LED if the associated
fan-tach sensor has a lower critical threshold event status asserted. Fan-tach sensors are
manual re-arm sensors. Once the lower critical threshold is crossed, the LED remains lit until
the sensor is rearmed. These sensors are rearmed at system DC power-on and system reset.
10.7 Memory Fault LEDs
The server board includes a Memory Fault LED for each DIMM slot. When the BIOS detects a
memory fault condition, it sends an IPMI OEM command (Set Fault Indication) to the BMC to
instruct the BMC to turn on the associated Memory Slot Fault LED. These LEDs are only active
when the system is in the ‘on’ state. The BMC will not activate or change the state of the LEDs
unless instructed by the BIOS.
10.8 CPU Fault LEDs
The server board includes a CPU fault LED for each CPU socket. The CPU Fault LED is lit if
there is an MSID mismatch error is detected (that is, CPU power rating is incompatible with
the board).
