Resetting the Switch

Resetting the Switch
These are reasons why you might want to reset the switch to the factory default settings:

You installed the switch in your network and cannot connect to it because you assigned the wrong IP address.

You want to reset the password on the switch.
Note: Resetting the switch deletes the configuration and reboots the switch.
Caution: If you press the Express Setup button when you power on, the automatic boot sequence stops, and the
switch enters bootloader mode.
To reset the switch:
1. Press and hold the Express Setup button (recessed behind a small hole in the faceplate) for about 10 seconds with
a paper clip or similar object. The switch reboots. The system LED turns green after the switch completes rebooting.
2. Press the Express Setup button again for 3 seconds. A switch 10/100/1000 Ethernet port blinks green.
The switch now behaves like an unconfigured switch. You can configure the switch by using the CLI setup procedure
described in Configuring the Switch with the CLI Setup Program, page 57

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 Recover Passwords, page
The Cisco IE 4010 Switch Software Configuration Guide provides details about enabling and disabling the password
recovery feature and the procedure for recovering passwords.

Finding the Switch Serial Number

If you contact Cisco Technical Assistance, you need to know the serial number of your switch. The serial number is on
the top of the switch. You can also use the show version command to obtain the switch serial number.
