System is (DC) powered on – The BMC calculates Dynamic Power Supply Redundancy status
based upon current system load requirements as well as total Power Supply capacity. The
BMC allows redundancy to be configured on a per power-unit-redundancy sensor basis by
means of the OEM SDR records.
5.3.17 Component Fault LED Control
Several sets of component fault LEDs are supported on the server board. See the figures for
Intel® Light Guided Diagnostics. Some LEDs are owned by the BMC and some by the BIOS.
The BMC owns control of the following FRU/fault LEDs:
Fan fault LEDs – A fan fault LED is associated with each fan. 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.
DIMM fault LEDs – The BMC owns the hardware control for these LEDs. The LEDs
reflect the state of BIOS-owned event-only sensors. When the BIOS detects a DIMM
fault condition, it sends an IPMI OEM command (Set Fault Indication) to the BMC to
instruct the BMC to turn on the associated DIMM 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.
Hard Disk Drive Status LEDs – The HSBP PSoC* owns the HW control for these LEDs
and detection of the fault/status conditions that the LEDs reflect.
CPU Fault LEDs – The BMC owns control for these LEDs. An LED is lit if there is an
MSID mismatch (that is, CPU power rating is incompatible with the board).

5.3.18 NMI (Diagnostic Interrupt) Sensor
The BMC supports an NMI sensor for logging an event when a diagnostic interrupt is
generated for the following cases:
