Transferring Software and Configuration Files
This section provides procedures for:
• Installing new software releases on the LA-210 unit
• Transferring configuration files.
Two software versions are stored, each of them in one of the two partitions of
the flash memory, which also contains a boot program. The software is stored in
a compressed format. The active version is decompressed and loaded into the
unit’s RAM upon power-up. The passive software is kept for backup purposes. If
the active software becomes corrupted, you can swap it with the backup. By
default, the unit is delivered with active software only.
New software releases are distributed as *.img files, which can be downloaded to
the LA-210. When starting a download, the current backup is erased and the new
software placed in the backup partition. When downloading is complete, the unit
checks the integrity of the new software file. If it is correct, the backup and
active files are swapped. The new software release becomes active and the
former active software becomes the backup. If a failure occurs while
downloading, the new version is erased. In this case, only one version is left
stored in the flash memory.
Configuration files can be uploaded for storage and backup.
