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:
 The front panel diagnostic interrupt button is pressed.
 The BMC receives an IPMI command Chassis Control that requests this action.
Note that the BMC may also generate this interrupt due to an IPMI Watchdog Timer
pre-timeout interrupt; however an event for this occurrence is already logged against the
Watchdog Timer sensor so it will not log an NMI sensor event.
5.3.19 LAN Leash Event Monitoring
The Physical Security sensor is used to monitor the LAN link and chassis intrusion status. This
is implemented as a LAN Leash offset in this discrete sensor. This sensor monitors the link
state of the two BMC embedded LAN channels. It does not monitor the state of any optional
NICs.
