Description Use the
bootrom update file command to upgrade software on an ADSL2+
card.
By default, the entire BootROM is upgraded.
This feature is only valid for ADSL2+ cards with CPUs.
The upgradeable software includes Boot ROM and ADSL2+ card software. Before
you do that, you first need to FTP or load the new software file by other means to
the Flash or CF card on your device and save it. Before performing an upgrade,
you need to shut down the interface with the shutdown command if the
interface is up. After completing the upgrade, you need to bring the interface up
with the undo shutdown command.
