Updating Software Releases

This section presents procedures for installing new software releases into the ASMi-52 units, as well as swapping existing software versions in a local or remote unit.

ASMi-52 stores two software versions, each of them in one of the two 512-byte 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 ASMi-52 RAM upon power-up. The passive software is kept for backup purposes. By default, ASMi-52 is delivered with the active software only.

New software releases are distributed on diskettes as an *.img file, which is downloaded to the local ASMi-52 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.

Installing a New Software Release via TFTP

1.From the SW & File Transfer menu, select TFTP (Figure 4-46) (Main menu > File Utilities > SW & File Transfer > SW Download > TFTP).
