Table 7-33: Bused Resource Status Command
Graceful Reset
The IPMC supports the Graceful Reboot option of the FRU Control command. On receiving
such a command, the IPMC sets the Graceful Reboot Request bit of the IPMC status, sends a
status update notification to the payload, and waits for the Graceful Reset command from
the payload. If the IPMC receives such a command before the payload communication time-
out time, it sends the 0x00 completion code (Success) to the carrier controller. Otherwise
the 0xC3 completion code (Time-Out) is sent.
