8.1 Resetting the device to default settings with the button (in the

startup phase)

NOTICE

Connection hazard - risk of communication failure

Depending on the con󹪝guration of your network, a reset device can cause circular frames and

thus the loss of data tra󹪟c.

NOTICE

Con󹪝guration hazard - risk of data loss

If a CLP is inserted in the device, the CLP is also reset to default settings.

Note

When you reset the device to the default settings, all con󹪝gurations are deleted, including:

• The IP address

• The created user

• The passwords

• The user-de󹪝ned keys and certi󹪝cates

Following this, the device can only be reached via the serial interface.

If you assign an IP address to the device via DHCP or DCP (e.g. SINEC PNI), you can access the CLI

and WBM of the device via a network connection with a preset user pro󹪝le.

Note

Reset despite disabled "SELECT/SET" button

Using the "SELECT/SET" button, you can always reset the device parameters to the factory

settings during the startup phase of the device. This applies also if the "Reset to Factory Defaults"

function was disabled in the con󹪝guration. This allows you to reset the device to the factory

defaults in an emergency.

If the function has been disabled in the con󹪝guration, it is only disabled on completion of the

startup phase.
