IPMC Operational Code Firmware Update Modes
There are two update modes:
The following section provides an overview of the staged update process.
IPMC firmware image delivered in the firmware bundle also contains the image of
onboard FPGA. If during the update procedure IPMC detects that newly loaded IPMC
firmware image contains newer FPGA version then the one running on the board, the
new FPGA will be loaded. Due to FPGA serving major functionalities on the payload the
board will be automatically rebooted in order to assure proper board operation.
• Direct Update Mode - This upgrade procedure updates IPMC firmware directly to
• Staged Update Mode - The Staged Update feature allows the IPMC operational

the internal flash on the IPMC. The user does not have the ability to back up the
“old” operational image.
code to be updated while the system is online (OS is running). After saving copy of
currently running IPMC image, the new image is loaded to stage area. Upon
completion of the upgrade teh image is copied to the internal flash of the IPMC. If
the switchover fails, or at the user's discretion, the firmware may be rolled back to
the previous version.
The advantage of running this mode is that the user can store the old firmware
image to a rollback region (for redundancy purposes). A pending firmware update
may also be created allowing the user to continue to use the current firmware
before the actual update.
