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
