Release Notes for the Catalyst 3750 Switch Cisco IOS Release 12.1(14)EA1

OL-4215-01

New Features

Clearing the Switch IP Address and Configuration

If you have configured a new switch with a wrong IP address, or all the switch LEDs start blinking when

you are trying to enter Express Setup mode, you can clear the IP address that is configured on the switch.

Note This procedure clears the IP address and all configuration information stored on the switch. Do not

follow this procedure unless you want to completely reconfigure the switch.

To clear the IP address and the switch configuration information, follow these steps:

Step 1 Press and hold the Mode button, as shown in Figure 1 on page 8.

The switch LEDs begin blinking after about 2 seconds.

Step 2 Continue holding down the Mode button. The LEDs stop blinking after 8 additional seconds, and then

the switch reboots.

Note These steps only works on a previously configured switch.

Where to Go Next

After you have saved your configuration to the switch, you can install the switch (refer to the switch

hardware installation guide) or further configure it (refer to the switch software configuration guide).
