Restart with the SELECT/SET button disabled for "Restore Factory Defaults"
If you have disabled the SELECT/SET button for "Restore Factory Defaults" in the
configuration, this does not apply during the startup phase. When you restart after cycling
power, the configuration can nevertheless be deleted using this button. This action cannot
be undone and you then need to reload the device configuration. This can lead to
disturbances and failures in the corresponding network area.

power supply. Deviations from this status are displayed as errors/faults.

2. Hold down the "SELECT/SET" button for 5 seconds.
Enabling/disabling the redundancy manager
To enable/disable the redundancy manager, follow the steps below:
