4.3.4 Upgrading System Firmware
Each MLNX-OS software package version has a default switch firmware version. When you
update the MLNX-OS software to a new version, an automatic firmware update process will be
attempted by MLNX-OS. This process is described below.
4.3.4.1 After Updating MLNX-OS Software
Upon rebooting your switch system after updating the MLNX-OS software, MLNX-OS com-
pares its default firmware version with the currently programmed firmware versions
on all the
switch modules (leafs and spines on director-class switches, or simply the switch card on edge
switch systems).
If one or more of the switch modules is programmed with a firmware version other than
the
default version, then MLNX-OS automatically attempts to burn the default firmware version
instead.
To verify that the firmware update was successful, log into MLNX-OS and run the command
“show asic-version” (can be run in any mode). This command lists all of the switch modules
along with their firmware versions. Make sure that all the firmware versions are the same and
match the default firmware version. If the firmware update failed for one or more modules, then
the following warning is displayed.
Some subsystems are not updated with a default firmware.

.4.2 Importing Firmware and Changing the Default Firmware
To perform an automatic firmware
update by
MLNX-OS for a different switch firmware version
without changing the MLNX-OS version, import the firmware package as described below.
MLNX-OS sets it as the new default firmware and performs the firmware update automatically
as described in the previous subsections.
switch (config)# no boot next fallback-reboot enable
switch (config)# image boot next
switch (config)# configuration write
switch (config)# reload
If a firmware update takes place, then the login process is delayed a few minutes.
If you detect a mismatch in firmware version for one or more modules of the switch
system, please contact your assigned Mellanox Technologies field application engi-
neer.
