To reset a Cisco Catalyst 2948G switch to factory defaults do the following:

[CAUTION: This will RESET the switch to factory settings!]


1. Connect via serial to console port (Use these terminal settings-9600 baud rate/No parity/8 data bits/1 stop bit)


2. Turn off the switch, and then turn the switch back on

      Wait a few minutes after the power reset, if necessary, for the switch to present the first password prompt.


Important: After the presentation of the first password prompt, you have 30 seconds to complete the recovery procedure that follows in Steps 3–7. Because you only have 30 seconds to complete this procedure, press Enter whenever the switch prompts you for an old or new password. This action is the equivalent of the entry of a null character and allows you to complete the recovery quickly.

A failure of any of the steps that follow indicates that you have exceeded the 30-second time limit. If you exceed the limit, you need to power off/on the switch again. You need to return to Step 3 and start the procedure over.


3. Press Enter at the password prompt to enter a null password

4. Type enable at the prompt to enter enable mode.

5. Press Enter at the password prompt to enter a null password.

6. Type clear config all

      This command will clear all configuration in NVRAM.

This command will cause ifIndex to be reassigned on the next system startup.

System configuration cleared.

7. Then type set password and enter password

8. The type set enablepass and enter this password.

After the configuration erase in CatOS, you do not need to reload the switch. The configuration takes effect immediately, and the switch returns to the factory default configuration.
