These commands can beused to force the front panel LED and fan speed state, and to sense the state of the front panelbuttons without causing the BMC firmware to act on changes to them (button pushes).Each command request takes a signal type, a signal instance (to allow for supporting multiplesignals of a particular type), and an action to perform. The signal types are guaranteed to beconsistent across platforms, although some platforms may introduce new signal types forplatform-specific signals that can be accessed by these commands and may not providesupport for others that are not appropriate for the platform.Table 20 shows outputs that can be tested via the Set SM Signal command.Table 20.
