The firmware on the Cyclades TS2000 terminal server was upgraded from 1.3.4 to 1.3.6 today.

Some problems arose with the RADIUS authentication: the files /etc/raddb/server, /etc/pam.conf, and /etc/motd were not in the config_files list and were not saved. Changing these back to appropriate versions worked.

Point to remember: it is a good idea to tar up the /etc directory and save it on another system before upgrading the firmware. This gives a good backup of all the configuration files in case the upgrade procedure touches more than the release notes say it will.

Rather than using the FTP download for the upgrade images, I downloaded them to my workstation (via FTP) and then copied them to the TS2000 using scp from the console.
