8.1.3 Setting the Computer to the Standard Network Settings of the
Power Reducer Box
Changing network settings
Do not change any of the network setting values if you are not sure of the consequences of the
changes. It is possible to adjust the settings in such a way that your existing network no longer
works at all or only partially. In the worst case, the computer will no longer be able to
communicate with the Power Reducer Box. In order to be able to make changes to the network
settings, you will require the necessary user rights on the computer. If in doubt, contact your
network administrator.
