(for example, the connection between the 
computer and the Switch is lost while the new 
firmware is being copied to the Switch).

A progress screen displays while the upgrade is 
taking place.

The upgrade procedure can take a few 
minutes, and is complete when the progress 
bar has finished running and the Power LED 
has stopped flashing and is permanently green. 

To reset the Switch to factory default settings:

Click Administration, then Initialize on the 
menu. 

You will lose all your configuration changes. 
The Switch LAN IP address will revert to the 
default IP address 169.254.x.y. (see 

). You may need 

to restart your computer to re-establish 
communication with the Switch.

Clicking on Administration, then Reboot on the 
menu has the same effect as power cycling the 
unit. No configuration information will be lost. 
Reboot the Switch if you are experiencing 
problems and you want to re-establish your 
Internet connection.

Any network users that are currently accessing 
the Internet will have their access interrupted 
while the reboot takes place, and they may 
need to restart their computers when the 
reboot has completed and the Switch is 
operational again.
