Component Fault LED Control
Several sets of component fault LEDs are supported on the server board (see Figure 70 and Figure 71). Some
LEDs are owned by the BMC and some by the BIOS. A description of these LEDs is below and in Table 51.
•
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 does not activate
or change the state of the LEDs unless instructed by the BIOS.
•
HDD status LEDs – The HSBP PSoC* of supported Intel and non-Intel chassis owns the hardware con-
trol 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
where the CPU power rating is incompatible with the board.
