11.8 Restart, recovery procedure, and flashing the firm-
ware
The device must be restarted in order to perform a recovery procedure or to flash the firm-
ware.
11.8.1 Performing a restart
Objective The device is restarted with the configured settings.
Action • Press the ON/OFF button of the device already started for approximately 5 s to switch
off the device. (Alternatively, disconnect the power supply and then connect it again.)
• Then press the ON/OFF button again shortly to restart the device.
11.8.2 Performing a recovery procedure
Objective (up to 8.3.x) Up to mGuard firmware version 8.3.x
The network configuration (but not the rest of the configuration) is to be reset to the de-
livery state, as it is no longer possible to access the device.
Use the recovery procedure in case you have forgotten the IP address under which the de-
vice can be accessed.
The following network setting is restored:
The device is reset to router mode with the fixed IP address.
– The CIFS integrity monitoring function is also disabled because this only works when
the management IP is active.
– In addition, MAU configuration is activated for the Ethernet connections. HTTPS ac-
cess is enabled via the local Ethernet connection (LAN).
– The settings configured for VPN connections and the firewall are retained, including
passwords.
Possible reasons for performing the recovery procedure:
– The device is in PPPoE mode.
– The configured IP address of the device differs from the default setting.
– The current IP address of the device is not known.

NOTE: After the recovery procedure has been performed successfully, a previously cre-
ated configuration profile in the device should be loaded and activated again. Then the
network settings must be adapted.
Up-to-date information on the recovery and flashing procedure can be found in the appli-
cation note for your mGuard firmware version. (Application notes are available in the
