Updating the BMC firmware

Use the baseboard management controller (BMC) firmware update utility program to
download a BMC firmware update or a sensor data record/field replaceable unit
update. The firmware update utility program updates the BMC firmware or
SDR/FRU data only and does not affect any device drivers.
Go to http://www.ibm.com/support/ to download the utility program; then, copy the
flash.exe file to a firmware update diskette.
Note: To ensure proper server operation, be sure to update the server BMC
power supplies installed. A server with a single fixed power supply will have
one power supply and no fans on the rear of the server.
