SSUA Initialization
An SSUA startup script is added to the data plane initialization scripts.
Local Software Upgrade
It is possible to upgrade software components locally via RedBoot*. This type of
upgrade can be performed via the debug Ethernet port (using TFTP) or via the serial
console (using Xmodem) and requires operator intervention.
To make this operation as simple as possible, it is performed in the Boot Monitor (the
booting procedure has to be stopped on the Boot Monitor’s command line interface). To
perform a single image upgrade (note that only this kind of update is possible when
upgrading locally), the operator has to perform two operations:
Since writing the image to flash can be performed in a number of ways in the Boot
Monitor, it is very important that this operation does not disrupt any of the SSUA
functionality. To ensure that local software upgrade operations are transparent to the
SSU functionality, some dedicated commands have been introduced:
Local software upgrade of the BMC image is supported by the NPU. The same upgrade
commands are used to load the image and start the upgrade process for the BMC code.
After loading a BMC image to NPU RAM, communication with the BMC is started and the
image is passed to the BMC controller local memory. The BMC operational code selects
and writes the image to the inactive partition on its flash. This is possible because there
is a local copy of the image status words present on the BMC. After successful storage
of the image, the operator has to issue a “switch image” command to run this image in
one-shot mode after the next reboot.
Local Software Upgrade Procedure
This procedure covers the upgrade of the firmware on IXB2850 boards that contain an
earlier version of the firmware. Check the software Release Notes for a list of the
components to be upgraded for a specific release.
The procedure relies on the Local SSU mechanism (as described above in
Section
debug network interface should be operational and configured.
Substitute the appropriate XModem load commands when upgrading via the serial line
if preferred by the system setup.
The procedure for upgrading from earlier versions of the firmware is basically the same,
but the components to be upgraded are slightly different.

generation and newer boards respectively.
• Load the selected image to local RAM
• Issue a command to write this image into flash
• ssu upgrade - Selects image storage by checking the status word for the selected
• ssu get info - Returns properties of the selected image type
• ssu setcfg - Runs the upgraded image in safe mode after the next board reboot
• ssu validate - Validates the configuration running in safe mode
