Resetting to Factory Defaults
If the Switch does not operate normally or if the
firmware becomes corrupted, you can reset the Switch
to factory defaults.
CAUTION: Resetting the Switch to factory defaults
erases all your settings. You will need to reconfigure
the Switch after you reset it.
To reset the Switch to its factory defaults:
1 Using the tip of a pen (or a similar object), press the
Recovery button on the rear panel of the Switch. See
Figure 1 for illustration.
2 Power off the Switch, and then power it back on, while
keeping the Recovery button pressed.
3 Release the Recovery button.
4 Reset the Switch either by:
■ Accessing the Web interface using Discovery, and
then pressing the RESET button on the Initialize tab
of the Administration menu. After you click RESET, a
confirmation message appears. Click OK to confirm.
■ Powering off the Switch, and then powering it back
on.
The Switch will perform automatic IP configuration
after you reset it. See “Automatic IP Configuration” on
page 33 for more information.
Forgotten Password
If you forget the password to the Web interface after
you set it, you will need to reset the Switch to regain
access. See “Resetting to Factory Defaults” on page 71
for instructions.
