Juniper SRX100B Factory Reset Instructions

There are currently three ways you can reset your Juniper SRX100B back to the original factory configuration. Not only do these steps work for the device listed, they also work for any SRX branch series router. The methods consist of using the load factory-default command, using the reset config button, and using the root password recovery process.

Using the Load Factory-Default Command
If you are still able to log in to the SRX100B with the CLI, you can use the load factory-default command to return the security appliance to its original factory default configuration. The load factory-default command loads and commits the factory configuration, but using this command does not delete other configuration files on the device.

1. Type the load factory-default command.
   root@host# load factory-default


2. Use the set system root-authentication plain-text-password command to set a new root password for the device.
   root@host# set system root-authentication plain-text-password


3. Enter the root password, and enter it one more time for confirmation.
   New password:
   Retype new password:


4. Use the commit and-quit command to commit the configuration and exit from configuration mode if the configuration contains no errors and the commit succeeds. 
   root@host# commit and-quit
   
   After the commit, the factory default configuration is the running configuration.

Using the Reset Config Button
The reset config button may only be found on the SRX650, SRX240, SRX210 and SRX100.

You can use the Reset Config button on the front panel of the SRX Series product to reset your hardware to its factory default configuration. If you use the Reset Config button to reset the device to its factory default configuration, all the configuration files, including the backup configuration and rescue configurations, are deleted. Otherwise, this means they are gone forever.

To reset the your Juniper device to its factory default configuration, press and hold the Reset Config button on the front panel of the SRX Series device for at least 15 seconds, until the Status LED glows amber.


Using the Root Password Recovery Process
If you can no longer log in to your SRX device, you can use the root password recovery process to reset the device to its factory default configuration. You must have console access to use the password recovery process. Please follow these steps from 1 to 20 carefully.

1. Power off the router by pressing the power button on the front panel.
2. Turn off the power to the management device, such as a laptop or desktop computer, that you want to use to access the CLI.
3. Plug one end of the Ethernet rollover cable supplied with the router into the RJ-45–to–DB-9 serial port adapter supplied with the router.
4. Plug the RJ-45–to–DB-9 serial port adapter into the serial port on the management device.
5. Connect the other end of the Ethernet rollover cable to the console port on the router.
6. Turn on the power to the management device.
7. On the management device, start your asynchronous terminal emulation application (such as Microsoft Windows Hyperterminal) and select the appropriate COM port to use (for example, COM1).
8. Configure the port settings:  Bits per second = 9600, Data bits = 8, Parity = None, Flow control = None
9. Power on the router by pressing the power button on the front panel. Verify that the POWER LED on the front panel turns green. The terminal emulation screen on your management device displays the router’s boot sequence.
10. When the following prompt appears, press the Spacebar to access the router’s bootstrap loader command prompt:
    
    Hit [Enter] to boot immediately, or space bar for command prompt. Booting [kernel] in 9 seconds...

    Enter full pathname of shell or 'recovery' for root password recovery or RETURN for /bin/sh: recovery


13. Enter configuration mode in the CLI.
14. Set the root password. For example:
    
    user@host# set system root-authentication plain-text-password


15. At the following prompt, enter the new root password. For example:
    
    New password: Vology
    Retype new password: Vology


16. At the second prompt, reenter the new root password.>
17. After you have finished configuring the password, commit the configuration.
    
    root@host# commit
    commit complete
