Software Upgrade
Software upgrade allows you to obtain a target application file from the current host and set the file as
the main boot file or backup boot file to be used at the next reboot.
A boot file, also known as the system software or device software, is an application file used to boot the
device. A main boot file is used to boot a device and a backup boot file is used to boot a device only
when the main boot file is unavailable.
The software upgrade will take a period of time. During upgrading, do not perform any operation on the
Web page. Otherwise, the software upgrade is interrupted.
Select Device > Device Maintenance from the navigation tree to enter the software upgrade
configuration page, as shown in
Figure 1-1.
Figure 1-1 Software upgrade configuration page
