Appendix C Firmware Upgrade and Downgrade Procedures
Description of Upgrade/Downgrade Terminology
tftp put
The UNIX TFTP (Trivial File Transfer Program) is used to write firmware or backup boot code to the
ASC Flash or disk, and to the SM Flash.
Example:
tftp shelf
tftp> bin
tftp> put <file> AXIS_<FILE>.<EXTENSION>
tftp> quit
The number of bytes reported as being sent by the TFTP routine should be compared with the size of
the firmware or backup boot code file.
Example:
ls -l <file>
-rw-rw-rw- <size> <file>
tftp> put <file> AXIS_<FILE>.<EXTENSION>
Sent <size> bytes in <seconds>seconds
File Size
The firmware file size tends to be rather unique. The firmware file size can be used to verify that the
firmware file was successfully TFTP-put to the ASC disk.
Example:
shelf.1.<3|4>.ASC.<a|s>shellConn
shelf.1.<3|4>.ASC.<a|s> cd "C:fw"
shelf.1.<3|4>.ASC.<a|s> ll
size date time name
512 <date> <time> .
512 <date> <time> .
<size> <date> <time> ASC.FW
