Clearing the Switch IP Address and Configuration
If you have configured a new switch with a wrong IP address, or if all the switch
LEDs start blinking when you are trying to enter Express Setup mode, you can
clear the IP address that is configured on the switch.
Note
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 clear the IP address and the switch configuration information, follow these
steps:
Step 1
Press and hold the Mode button, as shown in
The switch LEDs begin blinking after about 2 seconds.
Note
If the switch is not configured, the LEDs are all green. You can omit Step
2 and run Express Setup to configure the switch.
Step 2
Continue holding down the Mode button. The LEDs stop blinking after 8
additional seconds, and then the switch reboots.
Note
These steps only work on a previously-configured switch.
The switch now behaves like an unconfigured switch. You can configure the
switch by using Express Setup as described in these sections.
