The IPMC does not reset the payload on receiving the Graceful Reset command or time-
out. If the IPMC participation is necessary, the payload must request the IPMC to perform a
payload reset. The Graceful Reset command is also used to notify the IPMC about the com-
pletion of the payload shutdown sequence.
Table 9-23: Graceful Reset Command
Diagnostic Interrupt Results
The IPMC supports the Issue Diagnostic Interrupt feature of the FRU Control command. The
payload is notified about a diagnostic interrupt over the SIPL. The payload is expected to
return diagnostic interrupt results before the payload communication time-out using the
Diagnostic Interrupt Results command of the SIPL.
Table 9-24: Diagnostic Interrupt Results Command
Get Payload Shutdown Time-Out Command
When the shelf manager commands the IPMC to shut down the payload (i.e. sends the Set
Power Level (0) command), the IPMC notifies the payload by asserting an appropriate alert
and sending an alert notification to the payload. Upon receiving this notification, the pay-
load software is expected to initiate the payload shutdown sequence. After performing this
sequence, the payload should send the Graceful Reset command to the IPMC over the Pay-
load Interface to notify the IPMC that the payload shutdown is complete.

4 If the payload responds before the payload communication
time-out, the diagnostic interrupt return code is forwarded to
the shelf controller as the completion code of the FRU Control
command response. Otherwise, the 0xCC completion code is
returned.
