If the Switch does not operate normally or if the firm-
ware becomes corrupted, you can reset the Switch to 
its factory defaults.

To reset the Switch to its factory defaults:

Using the tip of a pen (or a similar object), press the 
Recovery button on the rear panel of the Switch. See 

 for illustration.

Power off the Switch, and then power it back on, 
while keeping the Recovery button pressed.

Release the Recovery button.

Reset the Switch either by:

■

Accessing the Web interface using Discovery, and 
then pressing the RESET button on the Fail-Safe 
Mode screen (see 

). The Fail-Safe Mode 

screen appears (instead of the logon screen) after 
you perform steps 1 to 3 of this procedure. 

■

Powering off the Switch, and then powering it 
back on.
