3.15 FRU Payload Control
The MPCBL0001 implements the “FRU Control” command as specified in the PICMG 3.0
Specification. Through this command, the payload can be reset, rebooted, or have its diagnostics
initiated.
The FRU payload can be controlled by a command line via the Intel NetStructure
®
MPCMM0001
Chassis Management Module (CMM). The following CMM commands are supported by the
MPCBL0001.
Note: The user may issue an RMCP command to control the FRU payload as well. Refer to Table 108 on
page 189 for the associated IPMI command information.
3.15.1 Cold Reset
When this command is initiated, the board will perform a hard reset as described in Section 3.12.2,
“Hard Reset Request” on page 59 .
3.15.2 Warm Reset
When this command is initiated, the board will perform a soft reset as described in Section 3.12.3,
“Soft Reset Request” on page 59 .
3.15.3 Graceful Reboot
This specific payload control command is implemented using system interface messaging
capability and the SMS_ATN bit of the KCS status registers.
The Receive Message Queue is used to hold message data for system software until the system
software can collect it, while the SMS_ATN bit is used to indicate that the IPMC requires attention
from the system software.
The flow diagram below will assist the user who will be developing their system software to
interact with this command.
