CLI Command Reference
BV10-100 and BV10-1000 47
Operation Commands
load image
Description Loads a software upgrade/downgrade image from TFTP or FTP (using a
username and password) server. The BV10 acts as a client.
The BV10 can be upgraded or downgraded to the next or previous two
versions, preserving the unit’s settings. The unit can be upgraded or
downgraded more than two versions; however, there is no guarantee
that the unit’s settings will be preserved.
The upgrade/downgrade process preserves the unit’s current settings
such as IP parameters and Smart Loopback mode. As the software
loads, informative messages are displayed for each step, including
instructions when user input is required. If the installation fails, the unit
automatically reverts to the previous software image. Once the
software is loaded, the BV10 must be rebooted in order for the new
software image to be applicable. You can use either the RESET button
or the reboot command. Refer to RESET Button on page 21 and reboot
on page 45 for more information.
The LAN or the Test port can be used for loading a software image.
However loading a software image using the Test port stops all
applications running on the BV10, the following message is displayed
requiring a confirmation.
Test Port used to load the image. All Test Applications will be stopped during upgrade.
Are you sure you want to continue? (Y/N)
Enter
Y
to stop all applications and proceed with the image loading.
Enter N to cancel the command.
State and configuration settings are preserved and restored when the
software upgrade is complete and the BV10 is rebooted. The Ping test
remains enabled during software upgrades.
The load image command can be entered through the CONSOLE port
or the LAN/Test port running Telnet or SSH. Refer to Connecting to the
BV10 to a Console on page 30 for more information.
