Powering Modules Up And Down - Cisco Catalyst 2000 Configuration Handbook

The reset command causes an entire module to be powered down and then back up and
forces the module to go through Power-On Self-Test (POST) as it reloads. Some switches
do not offer this option. For those switches, you can reset a port with the shutdown and
no shutdown commands.

Powering Modules Up and Down

For modular switches, you can power down a module. Powering down disables the mod-
ule and all its ports. If the switch is reset or power-cycled, the module remains in a pow-
ered-down state. This state can be useful for troubleshooting a boot problem or if the
power supply cannot handle the complete switch power load:
(global) no power enable module slot
This command disables the modules. None of the module's configuration are saved, and
if the switch is reset, all the configuration entries for that module are lost. To reenable the
modules, use the following command:
(global)power enable module slot
3-5: File Management and Boot Parameters
■ Cisco operating systems have many files and file systems that require management.
■ File management consists of managing configuration files and operating system files.
■ File system commands replace many older file management commands.
■ File system commands enable you to view and classify all files, including files on
remote servers.
File system commands enable you to copy files with complete path information to
■
eliminate the need for system prompting.
Cisco platforms support various Flash and ATA file system types.
■
When copying various files into Flash memory, it is important to configure the switch
■
to boot the proper file with boot parameters.
Note Switches have a set of file system commands that facilitate file management. Cisco
refers to the file system as the IFS or IOS file system. This file system provides an
extremely powerful way to manage files within the switch devices and on remote systems.
To provide backward compatibility, many aliases map to older commands for file manage-
ment. See Table 3-3 at the end of this section for a listing of the older commands and the
IFS equivalent.
