Resetting a Device to Factory Defaults

If you lose the admin password, you can reset the device to its default settings. This action destroys any existing configurations but restores access to the device.

WARNING: Resetting the device deletes all existing configuration settings and disables all existing firewall and VPN services.

You can restore the device to its default settings in one of the following ways:

„Using a Console connection. For further information, refer to the Concepts & Examples ScreenOS Reference Guide.

„Using the reset pinhole on the back panel of the device, as described in the next section.

You can reset the device and restore the factory default settings by pressing the reset pinhole. To perform this operation, you need to either view the device status LEDs on the front panel or start a Console session as described in “Using a Console Connection” on page 28.

To use the reset pinhole to reset and restore the default settings, perform the following steps:

1.Locate the reset pinhole on the rear panel. Using a thin, firm wire (such as a paperclip), push the pinhole for four to six seconds and then release.

The STATUS LED blinks red. A message on the console states that erasure of the configuration has started and the system sends an SNMP/SYSLOG alert.

2.Wait for one to two seconds.

After the first reset, the STATUS LED blinks green; the device is now waiting for the second reset. The Console message now states that the device is waiting for a second confirmation.

3.Push the reset pinhole again for four to six seconds.

The Console message verifies the second reset. The STATUS LED glows red for one-half second and then returns to the blinking green state.

The device then resets to its original factory settings. When the device resets, the STATUS LED glows red for one-half second and then glows green. The console displays device-bootup messages. The system generates SNMP and SYSLOG alerts to configured SYSLOG or SNMP trap hosts.

After the device has rebooted, the console displays the login prompt for the device. The STATUS LED blinks green. The login and password are netscreen.

If you do not follow the complete sequence, the reset process cancels without any configuration change and the Console message states that the erasure of the configuration is aborted. The STATUS LED returns to blinking green. If the device did not reset, an SNMP alert is sent to confirm the failure.
