Locating the Switch Serial Number
Caution 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 reset the switch:
1. At the switch prompt, enter enable, and press Return or Enter.
2. At the Privileged EXEC prompt, switch#, enter setup and press Return or Enter.
The switch displays the prompt to run the initial configuration dialog. The switch now behaves like an
unconfigured switch. You can configure the switch by using the CLI setup procedure described in
Appendix D, “Configuring the Switch with the CLI-Based Setup Program.”
