3.15FRU 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.

Table 35. CMM Commands for FRU Control Options

FRU Control Options	MPCMM0001 equivalent command
Cold Reset	cmmset –l bladex –d frucontrol –v 0
Warm Reset	cmmset –l bladex –d frucontrol –v 1
Graceful Reboot	cmmset –l bladex –d frucontrol –v 2
Diagnostic Interrupt	cmmset –l bladex –d frucontrol –v 3

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.

3.15.1Cold 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.

3.15.2Warm 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.

3.15.3Graceful 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.
