Reverting To The Ex Series Switch Factory-Default Configuration Using The Request System Zeroize Command - Juniper EX4300 Series Hardware Manual

The factory-default configuration contains the basic configuration settings for the switch. This is the first
configuration of the switch and it is loaded when the switch is first powered on. For the factory-default
configuration file for your switch, see the hardware documentation for your switch.
TIP: You can run the EZsetup script to complete the initial configuration of the switch
reverting to the factory-default configuration. (The EZsetup script is available only on fixed
configuration switches, it is not available on modular switches.) For information on completing
the initial configuration using either the CLI or the J-Web interface, see
Configuring an EX Series Switch (CLI Procedure)
Switch (J-Web Procedure)
You can revert to the factory-default configuration by using the Menu button to the right of the LCD
panel on switches with LCD panel or by using the request system zeroize operational command or the load
factory-default configuration command. (If your switch model does not have an LCD panel, use these
commands.) You can also use the load factory-default command to revert to the factory-default
configuration file that contains all default settings
These procedures are described in the following sections:
Reverting to the EX Series Switch Factory-Default Configuration Using the request
system zeroize Command
The request system zeroize command is a standard Junos OS operational mode command that removes all
configuration information and resets all key values. The operation unlinks all user-created data files,
including customized configuration and log files, from their directories. The switch then reboots and
reverts to the factory-default configuration.
To completely erase user-created data so that it is unrecoverable, use the request system zeroize media
command.
CAUTION: Before issuing request system zeroize, use the
to back up the files currently used to run the switch to a secondary device. Using the
zeroize command will destroy Junos and OAM partitions and the switch may not boot.
