Downloading the New Software Release File to Optimux-34
This section presents procedures for installing new software releases into
Optimux-34, as well as swapping existing software versions. The Optimux-34
system software is stored in nonvolatile memory. There are two memory
partitions (referred to as 0 and 1) in which to store a set of software files. The
software is stored in compressed format. The active version is decompressed and
loaded into the Optimux-34 RAM upon power-up. The passive software is kept
for backup purposes. The user can select which partition is active and which
serves as backup. Optimux-34 is shipped with one active partition and a backup
partition with the same software. Each time software is downloaded, it
automatically becomes the active software, while the previously installed version
becomes the backup software. The previous active partition becomes backup
(with its previous version of the software).
Optimux-34 stores two software versions, each of them in one of the two
partitions of its flash memory, which also contains a boot program. The software
is stored in compressed format. The active version is decompressed and loaded
into the Optimux-34 RAM upon power-up. The passive software is kept for
backup purposes. By default, Optimux-34 is delivered with the active software
only.
New software releases as an *.img file, which is downloaded to the local
Optimux-34 using the TFTP or XMODEM protocol. Upon downloading, the new
software release becomes active, the former active software turns into backup,
and the former backup is erased.
If a failure occurs during downloading or decompression, the new version is
erased from the flash and the backup version becomes active. In this case, only
one version is left stored in the flash memory. If the active software becomes
corrupted, you can replace it with its backup.
This procedure is used to replace the current software version with the new
software release (OP-34.img).
