Using the Reset Config Button on the SRX 210 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. The 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.

You can change the default operation of the Reset Config button by limiting how the
button resets the services gateway:
By default, pressing and quickly releasing the Reset Config button loads and
commits the rescue configuration through the J-Web interface or the CLI. (For
details, see the JUNOS CLI User Guide.)
By default, pressing and holding the Reset Config button for 15 seconds or
more—until the Status LED blinks red—deletes all configurations on the device,
including the backup configurations and rescue configuration, and loads and
commits the factory configuration. (For details about the factory default settings,
see the JUNOS Software Administration Guide.)
