Launch the shell and run the following commands.
ipmitool.exe -I lanplus -U root -P calvin -H raw 0x30 0x30 0x01 0x00
ipmitool.exe -I lanplus -U root -P calvin -H raw 0x30 0x30 0x02 0xff 0x46
to revert to the default fan response:
run, raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x00 0x00 0x00 . And to check the status run, raw 0x30 0xce 0x01 0x16 0x05 0x00 0x00 0x00 command. The response to the fan status should either be 16 05 00 00 00 05 00 01 00 00 when default behavior is Disabled or 16 05 00 00 00 05 00 00 00 00 when Enabled
