7 The original sourcefile name of SW files is in the structure uX_Y_Z.bz, where u
is the unit type (a for AU, s for SU) and X.Y.Z is the version number.
8 destinationfile is the name of the file to be loaded. Use the SNMP write
community <SnmpWriteCommunity>.bz to define the destination filename.
The default SNMP write community is private. For example, to load the
upgrade file a4_0_13.bz to an AU whose IP address is 206.25.63.65: tftp -i
206.25.63.65 put a4_0_13.bz private.bz
9 When the loading is complete, the following message is displayed, indicating
completion of the TFTP process:
Download operation has been completed successfully
10 The unit decompresses the loaded file and checks the integrity of the new
version. The new version replaces the previous shadow version only after
verification. If verification tests fail, the loaded version will be rejected. Among
other things that are tested, the unit will reject a file if either the file name or
the version number matches the current Main versions. The unit will also
reject a file designated for a different unit type, e.g. an AU upgrade file with
the prefix a in the original file name will not be accepted by SUs.
11 The FLASH memory can store two software versions. One version is called
Current and the second version is called Shadow. The new version is loaded
into the Shadow (backup) FLASH memory. To check that the new firmware
was properly downloaded and verified, view the firmware versions stored in
the FLASH, as follows:
a From the Main Menu, select 2 - Unit Control.
b From the Unit Control menu, select 5 - Flash Memory Control.
c From the Flash Memory Control menu, select S - Show Flash Versions.
The following information is displayed:
