Description: The Primary Power input fault alarm mask is either on or off. When it is on, the server will not assert an Alarm condition on a fault in the Primary Power supply. Unlike other fault masks, the fault condition will continue to be visible in the Fault Status Byte. This mask capability is useful when performing system tests when only a single power input is available and an alarm would be undesirable. When the setting is off, the server will assert an Alarm condition in addition to setting the appropriate bit in the Fault Status Byte.
