Early in POST, the BIOS communicates a unique platform ID to the BMC and the BMC will confirm that the firmware installed matches the indicated platform type. If a platform mismatch occurs, the BMC will log an error to the SEL and configure the system fans to a predefined speed. Near the end of POST, the BIOS will again check for a platform mismatch and display a warning message on the video. To clear this error, new BMC firmware, SDRs and the BIOS should be loaded onto the system.
5.2Fan Control and Temperature Monitoring
The BMC monitors and controls system fans, with each fan having a tachometer sensor used to determine cooling system health. The fan subsystem has three states: sleep, nominal and boost. Nominal is the default state, in this state fan speeds are based on the ambient system temperature. A system temperature threshold is set via an SDR which, when exceeded, linearly ramps the fan speeds either until the fan speed reaches maximum saturation or the temperature reduces below the threshold. If the system temperature stays below the threshold, fan speed will ramp back to the default speed. If system temperature remains above the threshold the system may throttle memory to reduce heat dissipation. Fans are in the sleep state when no fan boost conditions exist and the system is in ACPI S1 sleep state. Table 11 describes when system fans enter the boost state.
