▼ Clear Faults Detected During POST

In most cases, when POST detects a faulty component, POST logs the fault and
automatically takes the failed component out of operation by placing the component
in the ASR blacklist. See “Disabling Faulty Components” on page55.
In most cases, the replacement of the faulty FRU is detected when the service
processor is reset or power cycled. In this case, the fault is automatically cleared from
the system. This procedure describes how to identify a POST-detected fault and, if
necessary, manually clear the fault.
