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
Cables and Adapters, page 88 .
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 for about 10 seconds. 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 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-Based Setup Program, page 95 You can also configure the switch by
using Express Setup as described in the
Cisco IE 2000 Switch Getting Started Guide
.
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 76 .
The Cisco IE 2000 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 compliance label on the right-hand side of the switch. See
Figure 45 on page 77 . You can also use the show version
privileged EXEC command to obtain the switch serial number.
