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
To install 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).
