Resetting the Switch
Caution Resetting the switch reboots the switch.
To reset the switch to the factory defaults:
Step 1 If you are using Cisco IOS XE Release 3.6.0E or later releases, enter the erase startup-config privileged
EXEC command to clear the contents of your startup configuration.If you are using an earlier release, you
can skip this step.
Step 2 Press and hold the Mode button. The switch LEDs begin blinking after about 3 seconds.
Step 3 Continue holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the
switch restarts.
Step 4 The switch now operates like an unconfigured switch. You can enter the switch IP information by using
Express Setup as described in the “Running Express Setup” section on page 3.
