In case that you cannot upgrade the system software with the general upgrade procedure,
you can upgrade it with the boot mode upgrade procedure. Before the boot mode
upgrade, please keep in mind the following restrictions.
• A terminal must be connected to the system via the console interface. To open the
boot mode, you should press <S> key when the boot logo is shown up.
• The boot mode upgrade supports TFTP only. You must set up TFTP server before
upgrading the system software in the boot mode.
• In the boot mode, the only interface you can use is MGMT interface. So the system
must be connected to the network via the MGMT interface.
