To invoke this option from the web interface, select “Firmware” from the
“Tools” menu and then click the
button. From the resulting
screen, press the button. Watch the screen for
any error messages and then reboot the unit to complete the process.
Note: Certain upgrades (depending on the initial version number)
make it difficult or impossible to reboot the system via the web
interface. In these cases, the system can be rebooted from the
command line (with the reboot command) or by power-cycling.
To perform this action from the command line, invoke the upgrade script with
the argument ­­force­factory­settings:
eam999 ~ # upgrade --force-factory-settings
Watch the screen for any error messages and then reboot the unit to complete
the process.
5.5 Upgrade logs
The upgrade process stores all progress and error messages in the file
/var/log/upgrade.log. If you suspect that there has been a problem with
an upgrade or you wish to have full details of what has changed, you can
inspect this file by issuing the command
eam999 ~ # less /var/log/upgrade.log
You can scroll forward through the file simply by pressing the
key. For more control, you can move forward and
backwards, line by line, with the and keys or, page by page, with the
and keys.
The key should be used to return to the command line.
If you wish to obtain a copy of this log file, it can be copied from the system to
an external computer either via the serial port (see section 11.3.1.4 on page
157) or over the network (see section 11.3.1.2 on page 152).
