How to Clear the Switch IP Address and Configuration

Cabling Distance

If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable distance
from the switch to the connected device meets the recommended guidelines. See the “Cable and
Connectors” section on page C-1 for cabling guidelines.
How to Clear the Switch IP Address and Configuration
Follow these steps to return your switch to the factory default settings. These are reasons why you might
want to reset the switch:
• You installed the switch in your network and cannot connect to it because you assigned the wr ong
IP address.
• You want to clear all configurations from the switch and assign a new IP address.
• You want to reset the password on the switch.
Caution Resetting the switch deletes the configuration and reboots the switch.
To reset the password on the switch:
1. Power off the switch.
2. Power on the switch, and at the same time, press and hold down the Express Setup button until all
the system LEDs turn red.
3. Release the Express Setup button, and the switch continues to boot.
After the switch restarts, continue to run Express Setup.
The switch now behaves like an unconfigured switch. You can configure the switch by using Express
Setup as described in the getting started guide that is included with the switch. You can also configure
the switch by using the CLI setup procedure described in Appendix D, “Configuring the Switch with the
CLI-Based Setup Program.”
How to Recover Passwords
Password recovery is a feature that a system administrator can enable or disable. If password recovery
is disabled, the only way to recover from a lost or forgotten password is to clear the switch configuration
entirely. For this procedure, see the “How to Clear the Switch IP Address and Configuration” section on
page 3-5.
The switch software configuration guide provides details about enabling and disabling the password
recovery feature and the procedure for recovering passwords.
