ATCA-9305 User’s Manual

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 pay-
load reset. The Graceful Reset command is also used to notify the IPMC about the comple-
tion of the payload shutdown sequence.

Table 7-34:

 

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 7-35:

 

When the carrier controller 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 
payload 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 
Payload interface to notify the IPMC that the payload shutdown is complete.

If the payload responds before the payload communication

time-out, the diagnostic interrupt return code is forwarded to the 
carrier controller as the completion code of the FRU Control 
command response. Otherwise, the 0xC3 completion code (Time-
Out) is returned.
