Downloading Files from a TFTP Server
You can restore Avidia system files by downloading the files from a TFTP server. Prior to
downloading system files, it is recommended that you create a backup copy of your existing
image file (if it is valid), using an .alt file name extension. See “Copying Files” on page 356 for
instructions. Be sure to download a complete set of system files to prevent version conflicts
between files.
1Make sure the system from which you want to download files is running as a TFTP server.
2From the ::admin=> prompt, type the download command in the following format then
press .
download <remote host>:<full path to remote
file> <slot> [<file name>]
The system downloads the file and, if it is an image file, temporarily renames the file name
extension to .new until the file is booted and verified.
3Reset the card to which you downloaded the file(s) to load the new file(s) (unless you only
downloaded the cli.tcl file). See “Rebooting Cards” on page366 for instructions.
The system attempts to boot the image file that has the .new file name extension. If the
image file is valid, the system renames the file name extension to .bin and overwrites the
previous image file. If the new image file is not valid, the system attempts to boot the image
file that has the .bin file name extension. If that image file is not valid, the system boots the
backup copy of the image file that has an. alt file name extension (if you created one). If
the system cannot find a valid image file it loads the boot monitor, from which you can
download a new image file, and the management card fault LED lights.
Parameters
<remote host>
The IP address of the computer from which you want to download the file.
<full path to remote file>
The complete system path and filename of the file you want to download, using a forward
slash (/) to indicate a directory.
When restoring files, be sure to download a complete set of system files to
prevent version conflicts between files.
