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.
