Appendix A - Software Version Loading Using TFTP
tftp -i hostaddress put sourcefile [destinationfile]
where -i is for binary mode and hostaddress is the IP address of the unit to be
upgraded. put causes the PC client to send a file to the hostaddress.
7
The original sourcefile name of SW files is in the structure aX_Y_Z.bz, where
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 a5_0_15.bz to an AU whose IP address is 206.25.63.65: tftp -i
206.25.63.65 put a5_0_15.bz private.bz
When the loading is complete, the following message is displayed, indicating

completion of the TFTP process:
The unit decompresses the loaded file and checks the integrity of the new
10
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.
The FLASH memory can store two software versions. One version is called
11
Main 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
