Juniper EX4300 Series User Manual

1.
user@switch> request system zeroizewarning: System will be rebooted and may not boot without
configurationErase all data, including configuration and log files? [yes,no]
(yes)
2. Type yes to remove conguraon and log les and revert to the factory-default conguraon.
NOTE: The auto-image-upgrade statement is added under the [edit chassis] hierarchy level when
you use this procedure, and thus the automac image upgrade feature is made available on
the switch.
Reverng to the EX Series Switch Factory-Default Conguraon Using the load
factory-default Command
The load factory-default command is a standard Junos OS conguraon command that replaces the
current acve conguraon with the factory-default conguraon (except the root password seng,
which by default is not set but which you must set in order to commit the new conguraon in this
procedure).
If you want to run the EZsetup script to complete the inial conguraon of the switch aer you revert
to the factory-default conguraon, do not use the load factory-default command. Instead do the
reversion using either the LCD panel or the request system zeroize command. If you use the load factory-
default command to revert to the factory-default conguraon, the conguraon for the root password
is retained and the EZsetup script will not run. (The EZsetup script is available only on xed
conguraon switches, it is not available on modular switches.)
NOTE: The load factory-default command by itself is not supported on EX3300, EX4200, EX4500,
and EX4550 switches congured in a Virtual Chassis.
To revert to the factory-default conguraon by using the load factory-default command:
NOTE: If you use this procedure, you must delete the system commit factory sengs, set the
root password, and commit the conguraon. These steps are not required when you revert to
the factory-default conguraon by using request system zeroize. Also, the auto-image-upgrade
statement is not added to the conguraon when you use this procedure; it is added to the
conguraon when you use request system zeroize.
