When restoring a configuration onto a unit over an aggregated link,
■
communication with that unit may be lost because the restore
operation disables the aggregated link ports. Communication over the
aggregated links is re-established when the restore operation has
been completed.
When RADIUS is set as the authentication system mode for the Switch
■
and the configuration is saved, the shared secret (password) is not
saved and the system mode is saved as local. You must either edit the
saved configuration text file prior to restoring it, or reconfigure the
values using the CLI or Web interface after the Configuration Restore
has been completed.
For detailed descriptions of the Configuration Save and Restore Web
interface operations and Command Line Interface (CLI) commands, please
refer to the Management Interface Reference Guide supplied in HTML
format on the CD-ROM that accompanies your Switch.
Your Switch has an image of the Switching software residing in Flash
memory. During the software upgrade process the loading software
image will always over-write the existing software image. In the event of
a software upgrade failing you must completely reinstall the image to
avoid potential complications. You will not be able to run a corrupted or
missing software image.
The CD-ROM supplied with your Switch includes a Software Update
Utility that can be used to update the management software of the
Switch. The Utility should only be used if a previous upgrade has failed,
and you are unable to communicate with the Switch using the web
interface or command line interface. You can find the Utility in the Utility
directory on the CD-ROM.
For a detailed description of how to upgrade the software on your Switch
please refer to the Management Interface Reference Guide supplied in
HTML format on the CD-ROM supplied with your Switch or on the 3Com
Web site.
CAUTION: 3Com strongly recommends that you use the TFTP Server as
the primary means of upgrading your Switch. The Software Update Utility
should only be used if a TFTP software upgrade has failed and the Switch
