Looks like it's still in the middle of the upgrade. It's probably trying to re-connect to the machine where you were running the upgrader from. I am not sure what the procedure is to resume the upgrade process from the Software Installer tool.
Actually, that log is from the SI tool rather than the console of the 3300? In which case, who knows what state the 3300 is in!

You can always do a manual install.

At this point you only have two choices... If the SI is still running, manually reboot the controller, it is going to either continue or fail. If it fails or SI is no longer running, you will most likely need to get a technician onsite and do a full manual software installation and database restore.
