Note You can also provide the image name a command line argument to the
PreUpgradeScript. If you do this, the script does not prompt for the image name.
Example:
launch -c /image/PreUpgradeScript upgrade<filename>
The switch reboots three times in approximately five minutes, and then displays the 2.1 image. The image has
the same configuration it had before the upgrade. The serial console displays the system logs.
The logs display the switch passing through each reboot state before it finally displays the 2.1 image. The
telnet or ssh window displays the logs until the switch reboots the first time.

2.3 Recovering from Upgrade Errors

In the unlikely event a power failure occurs during the file writing portion of the upgrade process the system
may no longer boot. The most likely symptoms would be the system continuously restarting or never showing
any activity on the serial console. Any system with these symptoms will need to be returned to the local
Symbol Service Center for repair. See the Symbol Service Web-site http
://www.symbol.com/services/msc/msc.html
If a serial console is attached to the system during the software upgrade process and the escape key is pressed
at during a specific stage of the process automatic loading will be stopped. If the following message is
displayed for more than 20 seconds, then a key was pressed. This problem can be rectified by pressing the
ENTER key to boot the image.
Note Power cycling the system when any of these screens appears will cause an
unrecoverable error just like a power failure.
