Resetting the Configuration File When the SRX210 Services Gateway Is Inaccessible

You can use the SRX210 Services Gateway's Reset Config button to restore the device's
configuration file when the current one is faulty or fails. You can also change the default
behavior of the Reset Config button.

Using the Reset Config Button on the SRX210 Services Gateway

If a configuration fails or denies management access to the services gateway, you can
use the Reset Config button to restore the device to the factory-default configuration or
a rescue configuration. For example, if someone inadvertently commits a configuration
that denies management access to a services gateway, you can delete the invalid
configuration and replace it with a rescue configuration by pressing the Reset Config
button.

NOTE:

The Reset Config button is recessed to prevent it from being pressed

accidentally.

The rescue configuration is a previously committed, valid configuration. You must have
previously set the rescue configuration through the J-Web interface or the CLI.

To press the Reset Config button, insert a small probe (such as a straightened paper
clip) into the pinhole on the front panel.

•

By default, pressing and quickly releasing the Reset Config button loads and commits
the rescue configuration through the J-Web interface or the CLI. The Status LED is solid
amber during this time.

•

By default, pressing and holding the Reset Config button for 15 seconds or more—until
the Status LED is solid amber — deletes all configurations on the device, including the
backup configurations and rescue configuration, and loads and commits the factory
configuration.
