Shutting Down or Starting Up a Module
You can shut down or power up a module by using the
poweroff module
or
no poweroff module
command
to specify the module by its slot number in the chassis.
To determine the slot number for a module, use the

Purging a Nonfunctioning Module from the Running
Configuration
You can clear the running configuration for a system controller, I/O, or fabric slot (slots 1 to 30) that is not

command in EXEC mode.
This command does not work on supervisor slots or on any I/O slot that currently has a powered-up
module.
Note
Use the
purge module slot_number runnning-config
command to clear the running configuration for the
specified I/O slot.
switch#
purge module 4 running-config
Before You Begin
Verify that either the system controller, I/O, or fabric slot is empty or that the module installed in the slot is
powered down.
For example, suppose that you create an IP storage configuration with an I/O module in slot 3 of Switch A.
This module uses an IP address. You decide to remove this I/O module and move it to Switch B, and you no
