In this case, you need to roll the version to the backup source version in BootROM
mode. The detailed procedure is the same as that of upgrading the version software in
BootROM mode. For details, see Upgrade Through BootROM.
l The device can start normally after upgrade, but a certain function cannot run normally,
and therefore the current version needs to be rolled back to the previous one.
In this case, you can adopt either of the following modes to roll back the version:
– Roll back the version through command lines. The detailed procedure is the same as
that of upgrading the version software in CLI mode. For details, see Upgrade
Through CLI.
– Roll back the version through Web. The detailed procedure is the same as that of
upgrading the version software in Web mode. For details, see Upgrade Through
Web.
– Roll back the version through CF card. The detailed procedure is the same as that of
upgrading the version software in CF card mode. For details, see Upgrade
Through CF Card.
– Roll back the version in one-click mode.
During the version rollback, note the following:
One-Click Version Rollbac
NOTICE
l If the folder does not exist, the One-clickversion rollback fails. You can specify the version
to be rolled back and the configuration file.
l Version rollback does not involve license rollback. If the license files are different in the
source and target versions, manually load the required license file according to the product
documentation after the rollback.
Upgrade operations:
1. Check whether the backup file (backcfg.zip) is available. The backup file should be in
the CFcard:/backupyyyyMMddHHmmss/ folder. If the backup file is unavailable, the
follow-up procedure cannot be performed.
